When you push down on the handle of a bicycle pump, the volume decreases but the number of molecules stays the same. This makes the air pressure in the pump decrease.

• true

• false

100 degrees Celsius would equal _____K (Kelvin).

• 273

• 100

• 373

• 32

As you heat up a gas in a closed container, the pressure will decrease.

• True

• False

For a gas at a constant pressure, if you decrease the temperature then the volume of the gas will also decrease.

• True

• False

The volume of a gas is inversely proportional to its kelvin temperature at a constant pressure

• true

• false

If you were to graph Boyle's Law you would be graphing temperature vs. volume.

• true

• false

When the product of two variables is constant, the variables are inversely proportional to each other.

• true

• false

  Boyle's Law describes situations in which the volume of a gas is changed at constant temperature.

• True

• False
