When air rapidly expands, its temperature normally _______. decreases. You just studied 29 terms!
What happens to the temperature of air when it expands quizlet?
What happens to its temperature? AS the air rises, it expands, so the volume of air increases. As the air expands, its temperature falls.
How does the peak frequency of radiant energy relate to the absolute temperature of the radiating source?
How does the peak frequency of radiant energy relate to the absolute temperature of the radiating source? The peak frequency increases as temperature increases.
Which one of these values is the lowest temperature?
absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.
On which temperature scale does the average kinetic energy of molecules double when the temperature also doubles?
The kelvin scale The kelvin scale effectively measures the vibration (average kinetic energy of molecules) so it makes sense that a doubling in the kelvin means a doubling in kinetic energy. On the other hand the Celsius scale is defined by the melting and boiling points of water (quite arbitrary).
What is condensation is condensation a warming or cooling process?
Is condensation a warming or cooling process? Condensation is when a gas becomes a liquid. It is a warming process.
What happens to the temperature of air as it rises?
Rising air experiences a drop in temperature, even though no heat is lost to the outside. The drop in temperature is a result of the decrease in atmospheric pressure at higher altitudes. If the pressure of the surrounding air is reduced, then the rising air parcel will expand.
What happens when air expands quizlet?
As air rises, it expands because air pressure decreases with an increase in altitude. When air expands, it cools adiabatically.
How does the temperature of a gas change when it is compressed when it expands?
How does the temperature of a gas change when it is compressed? expands? Increases when compressed and decreases when decreases when it expands. A row of dominoes is placed upright, one next to the other.
Is absolute 0 possible?
Physicists acknowledge they can never reach the coldest conceivable temperature, known as absolute zero and long ago calculated to be minus 459.67°F.
Is 0 Kelvin possible?
Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There's a catch, though: absolute zero is impossible to reach.
What happens to the temperature of an object when the particles are moving faster?
When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Why does kinetic energy increase as temperature increases?
When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Does evaporation heat or cool the air?
Evaporation is called a "cooling process" because it removes heat from the surrounding air. Evaporation in the atmosphere is a crucial step in the water cycle. Water on Earth's surface will evaporate into the atmosphere as energy is absorbed by liquid water.
What is sublimation quizlet?
sublimation. the phase change in which a substance changes from a solid to a gas or vapor without changing to a liquid first (ex. dry ice) deposition.
What happens when air expands?
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
What happens when air rises?
As air rises, air pressure at the surface is lowered. Rising air expands and cools (adiabatic cooling: that is, it cools due to change in volume as opposed to adding or taking away of heat). The result is condensation/precipitation.
When air expands it will?
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
When air is rapidly compressed why does its temperature increase?
The air's temperature increased when quickly compressed because work was done on the air so its internal energy increased causing an increase in temperature.
What happens when air is expanded?
So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.
How cold is space?
In fact, it doesn't actually have a temperature at all. Temperature is a measurement of the speed at which particles are moving, and heat is how much energy the particles of an object have. So in a truly empty region space, there would be no particles and radiation, meaning there's also no temperature.
What is the temperature inside a black hole?
Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.
Is absolute hot possible?
But what about absolute hot? It's the highest possible temperature that matter can attain, according to conventional physics, and well, it's been measured to be exactly 1,420,000,000,000,000,000,000,000,000,000,000 degrees Celsius (2,556,000,000,000,000,000,000,000,000,000,000 degrees Fahrenheit).
What happens to the temperature of air when altitude increases?
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
What happens to the temperature of an object when the particles are moving faster and increase its kinetic energy *?
The correct answer is A. When an object has particles that move rapidly, it gains more kinetic energy. This process generates more heat, which results in an increase in temperature.
When the kinetic energy of the air increases what happens to its temperature?
When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases. 2.
How is temperature and kinetic energy related?
RELATION BETWEEN AVERAGE KINETIC ENERGY AND TEMPERATURE: The temperature of a substance is directly proportional to the average kinetic energy of the substance particles. Because the mass of these particles is constant, the particles must move faster as the temperature rises.
Does evaporation decrease temperature?
Liquid molecules that have this certain threshold kinetic energy escape the surface and become vapor. As a result, the liquid molecules that remain now have lower kinetic energy. As evaporation occurs, the temperature of the remaining liquid decreases.
What is the difference between evaporation and vaporization?
Evaporation is nothing but a type of vaporization which mostly occurs at temperatures below the boiling point. Vaporization can change the state of matter from a solid or liquid to a gas. During evaporation, the liquid state of matter is turned directly into a gas.
What is sublimation geology quizlet?
When a substance turns from a solid to a gas skipping the liquid stage.
