Gas Laws and UNITS

Front

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

Back

The volume will decrease.

Front

What do Torr, mm Hg, and atm measure?

Back

They are units for pressure.

Front

Which of the following is NOT a unit of pressure: atm, torr, kPa, or ml?

Back

ml is NOT a unit of pressure.

Front

What are three ways to increase the pressure of a gas?

Back

Increase the temperature, pump in more gas, or decrease the volume.

Front

Which container will have a lower pressure if one is larger than the other?

Back

The larger container will have a lower pressure.

Front

What is the relationship between temperature and gas volume according to Charles's Law?

Back

As temperature increases, the volume of a gas increases.

Front

What is the formula for calculating pressure in a gas?

Back

Pressure = Force / Area.

Front

What happens to gas pressure if the volume is decreased while the temperature remains constant?

Back

The pressure will increase.

Front

What is Boyle's Law?

Back

Boyle's Law states that pressure and volume of a gas are inversely related at constant temperature.

Front

What is the standard unit of pressure in the SI system?

Back

The Pascal (Pa) is the standard unit of pressure.
