Pressure and Gas Laws

Front

What is pressure?

Back

Pressure is the force exerted per unit area on the surface of an object. It is measured in Pascals (Pa).

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant.

Front

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

Back

If the volume of a gas decreases, the pressure increases, assuming the temperature remains constant.

Front

What is Charles's Law?

Back

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

Front

What happens to the volume of a gas when its temperature increases?

Back

When the temperature of a gas increases, its volume increases, assuming the pressure remains constant.

Front

What is the relationship between temperature and pressure in gases?

Back

The pressure of a gas increases as the temperature increases, assuming the volume remains constant.

Front

What is the formula for Boyle's Law?

Back

The formula for Boyle's Law is P1V1 = P2V2, where P is pressure and V is volume.

Front

What is the formula for Charles's Law?

Back

The formula for Charles's Law is V1/T1 = V2/T2, where V is volume and T is temperature.

Front

What happens to the volume of a balloon when it is cooled?

Back

The volume of a balloon decreases when it is cooled, according to Charles's Law.

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which a substance has no thermal energy, equivalent to -273.15°C or 0 Kelvin.
