Gas Laws

Front

What is the relationship between pressure and volume in a gas?

Back

Inverse relationship: As pressure increases, volume decreases, and vice versa.

Front

What happens to the pressure of a gas when its volume decreases?

Back

The pressure increases.

Front

What happens to gas particles when the temperature increases?

Back

The particles speed up and move farther apart.

Front

Define Boyle's Law.

Back

At constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

Define Charles's Law.

Back

At constant pressure, the volume of a gas is directly proportional to its absolute temperature.

Front

What is the ideal gas law equation?

Back

PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

Front

What does it mean for two variables to be directly proportional?

Back

As one variable increases, the other variable also increases.

Front

What is the effect of increasing temperature on gas pressure at constant volume?

Back

The pressure increases.

Front

What is the gas constant (R) in the ideal gas law?

Back

R = 0.0821 L·atm/(K·mol) or 8.314 J/(K·mol).

Front

What is the significance of absolute zero in gas laws?

Back

At absolute zero (0 K), the volume of an ideal gas theoretically becomes zero.
