Gas Pressure Problems

Gas pressure is caused by

• Gas molecules heating up

• Gas molecules reacting with other gas molecules

• Gas molecules hitting the walls of a container

• Gas molecules hitting other gas molecules

Cooking gas containers are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will

• Increase

• Decrease

• Remain the same

• Decreases for some, while increase for others

The temperature of gas is held constant, while its volume is decreased. The pressure exerted by the gas on the wall of the container increases, because its molecules

• Strike the walls with higher velocities

• Strike the walls with large farce

• Strike the walls more frequently

• Are in contact with the walls for a shorter time

Gas Pressure increases when particles are

• Squashed into a smaller space

• Allowed to spread out into a larger space

Gas Pressure increases when a gas is

• Made colder

• Made hotter
