| Which of the following expands most when the temperature is lowered? Equal volumes of iron, wood, helium, or water at 4 degrees C? | Water at 4 degrees C |
Which expands more for comparable changes in temperature?
In most cases, which expands more for comparable changes in temperature? gases.
Which of the following normally warms up faster?
Iron warms up faster when heat is applied.
Which of the following forms of energy is most closely related to temperature?
Thermal energy and temperature are closely related. Both reflect the kinetic energy of moving particles of matter. However, temperature is the average kinetic energy of particles of matter, whereas thermal energy is the total kinetic energy of particles of matter.
Which of the following expands the most when the temperature is increased?
Helium 6. Which of the following expands most when temperature is increased? Reasoning: Helium expands more because it is a gas.
Which of the following generally expands more for an equal increase in temperature solids or liquids?
In general, liquids will expand more than solids with an equal increase in temperature.
Which gas expands the most when heated?
Neon has the highest expansion ratio with 1 to 1445.

What are 2 examples of thermal expansion?
Thermal expansion examples
- Cracks in the road when the road expands on heating.
- Sags in electrical power lines.
- Windows of metal-framed need rubber spacers to avoid thermal expansion.
- Expansion joints (like joint of two railway tracks).
- The length of the metal bar getting longer on heating.
Which has the greater specific heat capacity the filling of a hot piece of pie or the crust?
Which has the greater specific heat capacity; the filling of a hot piece of pie or the crust? The filling.
What temperature scales have equal sized degrees?
Which temperature scales have equal sized degrees? Which temperature scale has the smallest sized degrees? a. Fahrenheit scale.
Which of the following is most closely related to kinetic energy of molecules?
Final Answer: The average kinetic energy of the particles of a gas is most closely associated with (B) temperature.
How does the movement of particles of matter change when temperature increases?
With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement.
Which of these expand the most?
Solids have tightly packed molecules; hence, least movement of molecules takes place leading to minimal expansion. In liquids, the molecules are less tightly packed as compared to solids; hence, they expand more than solids. Molecules of gases have no bonding at all; therefore, gases expand the most among the three.
Which of these will expand more on heating a gold B Air C Water D iron?
(d) air. Molecules in the air are not bound to each other; hence, the average distance between the molecules will increase considerably when heated. Therefore, air will expand more on heating.
Which expands most for increases in temperature solids liquids or gases?
When the temperature of a substance is increased, its molecules jiggle faster and normally tend to move farther apart. This results in an expansion of the substance. Gases generally expand or contract much more than liquids. Liquids generally expand or contract more than solids.
Which will expands more solid liquid or gas?
Solution: Gases expand much more than the liquid and the solids. Like liquids, the gases do not have a definite shape, so they also have only the cubical expansion.
Which of these expands the most?
Solids have tightly packed molecules; hence, least movement of molecules takes place leading to minimal expansion. In liquids, the molecules are less tightly packed as compared to solids; hence, they expand more than solids. Molecules of gases have no bonding at all; therefore, gases expand the most among the three.
Which solid expands most on heating?
The higher the attraction between the molecules, the higher will be its expansion. As this attraction is the most in solids and the least in gases, solids expand the least and gases expand the most on being heated.
What is thermal expansion of gases?
The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion.
What is an example of thermal expansion in gases?
If the gas inside the balloon condenses into a volatile liquid at or around 77 K, the volume change will be even larger. Removing the balloon exposes the cold balloon to higher temperatures. The resulting thermal expansion fills the balloon to its original size again.
Why is the filling of a pie hotter than the pastry?
The molecules in the pastry and filling have the same average kinetic energy as the pie comes out of the oven. Despite the temperatures being equal, your tongue is still more likely to get burned by the filling than the crust, though. There are 2 principles behind this: thermal conductivity and specific heat capacity.
Which of the following supports the Second Law of Thermodynamics?
Which of the following supports the second law of thermodynamics? Energy tends to degrade, becoming of lower and lower quality. The second law of thermodynamics tells us that the amount of disorder, called entropy, is always increasing.
What is the difference between Celsius scale Fahrenheit scale and Kelvin scale?
Because the difference between the freezing point of water and the boiling point of water is 100° on both the Celsius and Kelvin scales, the size of a degree Celsius (°C) and a kelvin (K) are precisely the same. In contrast, both a degree Celsius and a kelvin are 9/5 the size of a degree Fahrenheit (°F).
Which two temperature scales have units of the same magnitude?
The Kelvin scale is related to the Celsius scale. The difference between the freezing and boiling points of water is 100 degrees in each, so that the kelvin has the same magnitude as the degree Celsius.
What happens to the energy of the molecules if the temperature is increased?
When temperature is increased, the kinetic energy of the particles increases and they start vibrating with greater speed.
What happens to the kinetic energy of particles of matter in solid liquid and gas as temperature increases?
A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them.
What happens to matter as temperature increases?
Temperature has a direct effect on whether a substance exists as a solid, liquid or gas. Generally, increasing the temperature turns solids into liquids and liquids into gases; reducing it turns gases into liquids and liquids into solids.
When you increase the temperature of a reaction?
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure.
Which of the following will expand more when heated to the same temperature?
Gas (c) Gas will expand more as the inter-molecular force of attraction in gas molecules is least and K.E. is maximum.
Which of the following will expand more when heated to the same temperature 03 a solid B liquid and C gas explain your answer?
Solution: Gas will expand more as the intermolecular forces of attraction in gas molecules is less and kinetic energy is maximum.
