Gas Behavior

When the graph relating two variables is a straight line passing through the origin, the variables are:

• directly proportional
• inversely proportional
• exponentially proportional
• not related.

If the sun shining through windows heats the air in a sealed room, what happens to the air pressure in that room?

• it increases.
• it decreases.
• it will vary.
• it remains constant.

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 is the same as 373 K (Kelvin).

• True
• False

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 the relationship of 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
