Gas Laws #2

Front

What happens to the volume of a gas when the temperature increases at constant pressure?

Back

The volume increases.

Front

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

Back

This is described by Boyle's Law: as pressure increases, volume decreases.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature at constant pressure.

Front

What is the effect of altitude on atmospheric pressure?

Back

Atmospheric pressure decreases as altitude increases.

Front

Why do sealed bags expand at higher altitudes?

Back

The atmospheric pressure is lower at higher altitudes, causing the gas inside the bag to expand.

Front

What happens to the volume of a gas when it is compressed at constant temperature?

Back

The volume decreases.

Front

What is the ideal gas law?

Back

The ideal gas law is 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 happens to the volume of a gas when the pressure increases at constant temperature?

Back

The volume decreases.

Front

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

Back

The gas constant (R) relates the pressure, volume, and temperature of an ideal gas.

Front

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

Back

As temperature increases, the volume increases (Charles's Law).
