Which statement is true?

• When the pressure of a gas increases, its density decreases.

• Generally, the density of a gas increases with an increase in pressure.

• The density of a gas is not related to pressure.

The volume of a sample of a gas at 273 ^oC is 200 liters. If the volume is decreased to 100 liters at constant pressure, what will be the new temperature of the gas?

• 0 K

• 546 K

• 273 K

• 100 K

A gas with a volume of 400 mL at 120 ^οC is heated until its volume is 700 mL.  What is the new temperature ( in degree Celsius) of the gas if the pressure is constant?

• 4 14.75 ^οC

• 687.75 ^οC

• 210 ^οC

• 68.57 ^οC

What law deals with pressure and temperature?

• Guy-Lussac's

• Boyle's law

• Charles'

If I want to do calculations for Charles' or Guy-Lussac's law, what scale should the temperatures be in?

• ^oF

• ^oC

• K

If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be

• 250 mL

• 204 mL

• 196 mL

• 160 mL

A gas at a temperature of 300 K has a pressure of 2 atm. If the temperature is increased to 600 K, what will be the new pressure, assuming volume remains constant?

• 1 atm

• 2 atm

• 4 atm

• 8 atm

Which of the following best describes Guy-Lussac's Law?

• The volume of a gas is directly proportional to its temperature at constant pressure.

• The pressure of a gas is directly proportional to its temperature at constant volume.

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

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