|
The molecules of a gas are in constant random motion. |
|
How would the motion be described for molecules of a gas? |
|
|
|
Changing the temperature of a gas, held at constant volume, changes the pressure exerted by the gas. |
|
What impact does increasing the temperature of a gas held at constant volume have on pressure? Use a conical flask with cling film covering the opening (flat) and place it in hot water. The cling film will dome showing gas volume has increased as particles spread out. If kept at a constant volume, this would result in increased pressure.
Use ice water to show the opposite effect of temperature. The cling film should curve downwards. |

|
The temperature of the gas is related to the average kinetic energy of the molecules. |

Students should be able to explain how the motion of the molecules in a gas is related to both its temperature and its pressure |
