Gas Laws and Properties

Flashcards based on lecture notes about gases and their properties.

Adding 4 moles of gas to a container with 1 mole of gas (constant volume) will result in what pressure change?

The final pressure will be five times greater than the initial pressure.

What happens to the partial pressure of oxygen in a sample of air when the temperature is increased?

It increases.

Boyle's Law can be used for which of the following?

Predicting the change in volume of an inflatable toy from summer to winter.

A sample of argon gas occupies 50 L at standard temperature. Assuming constant pressure, what volume will the gas occupy if the temperature is doubled?

100 L

All of the following statements underline the kinetic molecular theory of gases EXCEPT:

The average kinetic energy is proportional to the temperature of the gas in ºC.

The random collisions of molecules upon a surface are the cause of the observable _ that surface

Pressure on

What is diffusion?

The tendency of particles to move from areas of higher concentration to areas of lower concentration

A student in the back of the classroom opened a bottle of perfume. A few seconds later the teacher, who was standing in the front of the room, could smell the perfume. This can be explained in terms of:

Both evaporation and diffusion

Gases diffuse throughout available space because of the _ motion of molecules.

Random

If an ideal gas is in a container and the volume is increased, what would be the effect on the temperature and pressure of the gas?

Both temperature and pressure decrease.
