How does the density of air in a deep mine compare with the density of air at sea level defend your answer?
Density of air at the surface is less than the density of air in a deep min. The weight and pressure at the bottom of the mine is increases by adding the air filling up the mine. The greater pressure in a gas means greater density based on Boyle's law.
How does the pressure exerted by a liquid change with depth of the liquid How does the pressure exerted by a liquid change as the density of the liquid changes quizlet?
Pressure increases with depth. As the density of the liquid increases, the pressure exerted by the liquid also increases.
What happens to the air pressure inside a balloon when it is squeezed to half its volume assume constant temperature )?
At a constant temperature, the air pressure will double inside a balloon when it is squeezed to half its volume.
What do peaked roofs convertible tops and airplane wings have in common when air moves faster across their top surfaces quizlet?
What do peaked roofs, convertible tops, and airplane wings have in common when air moves faster across their top surfaces? The air moves faster across the top surface, and exerts less pressure than air below, which causes the object to be lifted, because of the pressure on top.
How does the volume of a completely submerged object compare with the volume of water displaced?
How does the volume of a completely submerged object compare with the volume of water displaced? The volume of the completely submerged object is equal to the volume of displaced water.
How does the pressure exerted by a liquid change with depth in the liquid?
The pressure exerted by a liquid is small just under the surface of the liquid. But as we go we deeper in a liquid the pressure of liquid increases. As the depth of liquid increases the weight of liquid column pushing down from above increases and hence the pressure also increases.
Does liquid pressure increase with depth?
The pressure exerted by a liquid increases with depth. This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. As you go deeper, the area of liquid exerting pressure increase thus it also increases the pressure.
What happens to the pressure in water as an object gets deeper?
This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .
What happens inside when an air filled balloon is squeezed?
When you squeeze an air-filled balloon, what happens inside? It doubles in volume.
Was there a change in the volume of the air inside the balloon if there was did it increase or decrease?
As the balloon warms the balloon expands and the density of the air inside the balloon decreases. The volume and temperature kept changing in a way that kept pressure constant.
What happens to the mass of the loaf of bread when you squeeze it what happens to its volume its density?
When you squeeze a loaf of bread, the mass does not change. The volume on the other hand does change. It becomes smaller, and when you decrease the volume of an object, the density increases. This means that the loaf of bread actually increases its density with the squeezing.
Why do the gondolas of the Falkirk Wheel See Figure 13.19 in the textbook have the same weight whether or not they carry boats?
Why do the gondolas of the Falkirk Wheel (see Figure 13.19 in the textbook) have the same weight whether or not they carry boats? The boats displace water out of the gondolas equal to their weights.
How does the water pressure 1’m below the surface of a small pond compare with the water pressure at the same distance below the surface of a lake?
Explanation of Solution As depth is same in small pond and huge lake of water, the water pressure is same. Though the volume of huge lake is large compared to the pond, the pressure at 1 m depth is same. Water pressure does not depend on volume.
What does it say about density of the object and the liquid if the object remains partially submerged?
The density of the object does not have to be less than the density of the fluid in order to float. It has to be less than or equal to the density of the fluid. If it is less than the fluid density, the object will float partially submerged.
How the pressure at a point in a liquid vary with a depth of the point B density of the liquid?
If the density of a liquid increases, the pressure at a point inside the liquid at a given depth increases as pressure is directly proportional to density.
How does the pressure at a point in a liquid vary with a depth of the point?
Solution : Pressure at a point is directly proportional to its depth from the surface of liquid i.e, Pahani `P alpha h and P=hrhog" where ". rho.
Does density increase with depth?
Density is lowest at the surface, where the water is the warmest. As depth increases, there is a region of rapidly increasing density with increasing depth, which is called the pycnocline . The pycnocline coincides with the thermocline , as it is the sudden decrease in temperature that leads to the increase in density.
Can the ocean crush you?
Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean's pressure can indeed crush you.
Why does deep water have more pressure?
That's because there's less air above you pressing down. Similarly, as you travel deeper in water, pressure increases. Underwater pressure is called hydrostatic pressure.
Why does an inflated balloon when untied and released move quickly across the room like a rocket Boyle’s Law?
In addition, the pressure of the gas inside the balloon becomes greater than the air pressure outside of the balloon. When you release the opening of the balloon, gas quickly escapes to equalize the pressure inside with the air pressure outside of the balloon. The escaping air exerts a force on the balloon itself.
Why does the volume of a balloon decrease when the temperature is decreased explain what happens to the gas particles in the balloon?
The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
What happens to the volume or size of a balloon as it rises in the air?
When a balloon goes up higher in the air, its size will increase. Since there's less air in the upper atmosphere, there's less stuff pushing back on the balloon, and hence the pressure is lower, which allows the balloon to expand.
When a balloon is inflated Where do you think the air pressure is highest inside or outside?
A balance of forces: The pressure inside an inflated balloon is greater than the pressure outside it. The balloon is stable because the expanding force due to the pressure difference is balanced by the contracting force exerted by the surface tension of the rubber.
Does the volume change when you squeeze a loaf of bread?
When you squeeze a loaf of bread, its mass does not change, but its volume does change – it gets smaller. This means that the density of the loaf gets larger.
How does the loss of weight of the object compare with the buoyant force of the water?
The weight loss of the object is equal to the weight of the water displaced. What is the buoyant force that acts on a submerged object equal to? The buoyant force is equal to the weight of the fluid displaced by the submerged object.
How does the a water pressure 1m below the surface of a small pond compare with the B water pressure at the same distance below the surface of a lake?
As depth is same in small pond and huge lake of water, the water pressure is same. Though the volume of huge lake is large compared to the pond, the pressure at 1 m depth is same. Water pressure does not depend on volume.
Where is the pressure greater one Metre beneath the surface of Taal lake or one Metre beneath the surface of a swimming pool?
since (ρ and h) are the same for both the lake and the swimming pool, the pressure at depth is the same.
What is the relationship between liquid pressure and the depth of a liquid and also between liquid pressure and density?
Pressure is directly proportional to depth. If we triple the depth, we triple the pressure.
When the density of an object submerged in liquid is greater than the density of the liquid in which it is immersed the object?
Hence the object will float in liquid 1 as the density of liquid 1 is more than that of the object while the object will sink in liquid 2 as the density of liquid 2 is less than that of the object.
How does the density of an object floating on a fluid compare to the density of the fluid?
The average density of an object is what ultimately determines whether it floats. If its average density is less than that of the surrounding fluid, it will float. This is because the fluid, having a higher density, contains more mass and hence more weight in the same volume.
