Gas Laws

Front

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

Back

The volume will decrease.

Front

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

Back

The pressure increases.

Front

How do you convert Celsius to Kelvin?

Back

Add 273 to the Celsius measurement.

Front

If a gas has a volume of 30.0 mL at 25.0°C, what is its volume at 50.0°C?

Back

32.51 mL.

Front

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

Back

As pressure decreases, volume increases (Boyle's Law).

Front

What is the formula for Charles's Law?

Back

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

Front

What is the ideal gas law equation?

Back

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

Front

What does the term 'absolute zero' refer to?

Back

The theoretical temperature at which a gas has zero volume, equivalent to -273.15°C or 0 K.

Front

What is the effect of increasing the number of gas particles on pressure?

Back

Increasing the number of gas particles increases the pressure, assuming volume and temperature are constant.

Front

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

Back

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