PVTN/ideal gas law review

Front

What happens to the volume of a gas when the temperature decreases?

Back

The volume of the gas decreases.

Front

Why can gas molecules be easily compressed?

Back

Gas molecules are far apart.

Front

What is the relationship between pressure and volume of a gas at constant temperature?

Back

If the pressure increases, the volume decreases.

Front

How many moles of gas are present if the pressure is 3.81 atm in a volume of 0.044 L at 25 degrees C?

Back

.0069 mol

Front

What does the kinetic theory of gases state?

Back

Particles are always in motion.

Front

What is the ideal gas law formula?

Back

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

Front

What happens to the pressure of a gas if its volume decreases while temperature remains constant?

Back

The pressure increases.

Front

Define absolute zero in terms of gas behavior.

Back

Absolute zero is the theoretical temperature at which gas particles have minimum energy and motion.

Front

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

Back

The volume increases.

Front

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

Back

R relates the pressure, volume, temperature, and number of moles of a gas.
