14.3 Behavior of Gases

Front

What happens to weather balloons as they rise higher in the atmosphere according to Boyle's Law?

Back

The pressure OUTSIDE of the balloon decreases and the balloon EXPANDS.

Front

What happens to the pressure of a gas if the volume of the container is decreased while keeping the temperature constant?

Back

The pressure from the gas will increase.

Front

What condition must be kept constant for Charles' Law to be valid?

Back

Pressure must be kept constant.

Front

What is the equation for Boyle's Law?

Back

initial pressure x initial volume = final pressure x final volume.

Front

What is the unit for Volume in the equation for Charles' Law?

Back

Liter.

Front

Define Boyle's Law.

Back

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

Front

Define Charles' Law.

Back

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

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

As volume increases, pressure decreases, and vice versa, when temperature is constant.

Front

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

Back

The volume of the gas increases.

Front

What is the formula for Charles' Law?

Back

(V1/T1) = (V2/T2), where V is volume and T is temperature in Kelvin.
