Question 1

Compressibility is the measure of how much the ________ decreases under __________

Answer 1

Volume and Pressure

Question 2

Why are gases easily compressed?

Answer 2

Because of the space between molecules.

Question 3

What are the three factors that affect gas pressure?

Answer 3

1. The amount of gas
2. The volume
3. The temperature

Question 4

As the amount of air, the volume, and the temperature double, what happens to pressure?

Answer 4

It also doubles

Question 5

What is Boyle’s Law?

Answer 5

P1 * V1 = P2 * V2

Question 6

What is Charles Law?

Answer 6

V1/T1 = V2/T2
As a constant temperature, volume is inversely proportional to pressure.

Question 7

What is Gay-Lussac’s law

Answer 7

P1/T1 = P2/T2
At a constant pressure, temperature is proportional to volume.

Question 8

What is the gas law?

Answer 8

(P1 * V)/T1 = (P2/V2)/T2
A single expression is used to relate the variables of gas

Question 9

What are all previous gas laws derived from?

Answer 9

The gas law

Question 10

Moles of gas are constant for what laws?

Answer 10

Boyles, Charles, Gay-Lussac, and the Gas law.

Question 11

What is the formula for the Ideal Gas Law?

Answer 11

PV = nRT

Question 12

What happens to the moles in the Ideal gas law?

Answer 12

We kept the moles of gas constant in the last example
but the mole’s change
