What are the 2 units for pressure?

What causes pressure?

If the number of collisions between gas molecules is

increased, what happens to the pressure?

When a balloon is warmed up, the pressure inside increases.

Why does this occur?

Which would have more pressure, a gas at 25K or a gas at 200K? In 1-2 sentences, use what you know about temperature and pressure to explain why this

occurs.

What is diffusion?

Draw a picture of the path that a gas molecule would take to get

from the front to the back of the room.

Gases diffuse through the air because their particles

move ___________ .

What type of mixture is formed when one gas fully diffuses into

another?

If gas molecules move at almost 800mph, why does it take several minutes to smell perfume across

a room?

Using arrows, describe the relationship between volume and

temperature.

P & V are ___________ related.

An empty can of coke is heated over a flame, and then quickly cooled. Would the pressure inside the can increase or decrease after it cooled?

At a constant temperature, a sample of O2 gas occupies a

volume of 20L at 16atm. What will the volume of the gas be if

the pressure is increased to 8atm.

The pressure of H2O gas is 760mmHg at 50K. What would

the final pressure be if the temperature was lowered to 25K?
