KMT, Gas Variables and Boyle`s Charles` Laws

Gas pressure is caused by

• gas molecules colliding with walls of container

• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers

Of these three states of matter, which one has the most kinetic energy? 

• Solid 
• Liquid 
• Gas

A hypothetical gas that perfectly fits all the assumptions of the kinetic molecular theory is known as

• real gas

• ideal gas

• imaginary gas

• perfect gas

Which of the following is an assumption of the kinetic-molecular theory of gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move around in an orderly manner.

• Average kinetic energy of the gas particles directly proportional with Kelvin temperature.

Which of the following is not a physical property of gases?

• absence of definite volume

• large density

• high compressibility

• fluidity

What will happen to the volume of a gas under constant temperature if the pressure increases?

• Increase
• Decrease
• Nothing
• Explosion!

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change
