Gas Laws Quiz

If the temperature of a gas in a closed container increases

• the pressure of the gas increases.

• the average kinetic energy of the molecules decreases.

• the molecules collide with the walls of the container less frequently.

• the volume decreases.

What are standard temperature and pressure conditions for gases?

• 0 C and 0 torr

• 0K and 760 atm

• -273 C and 1 kPa

• 273K and 101.3 kPa

How do gas particles respond to an increase in volume?

• increase in kinetic energy and decrease in temperature

• decrease in kinetic energy and decrease in pressure

• increase in temperature and increase in pressure

• increase in kinetic energy and increase in temperature

At constant pressure, the volume of a fixed mass of gas and its Kelvin temperature are said to be

• directly related.

• inversely related.

• unrelated.

• constant.

Increasing the volume of a given amount of gas at constant temperature causes the pressure to decrease because

• the molecules are striking a larger area with the same force.

• there are fewer molecules.

• the molecules are moving more slowly.

• there are more molecules.

The volume of a gas is doubled while the temperature is held constant. The pressure of the gas

• remains unchanged.

• is reduced by one half.

• is doubled.

• depends on the kind of gas.

Which of these changed would NOT cause an increase in the pressure of a contained gas?

• Another gas is added to the container.

• Additional amounts of the same gas are added to the container.

• The temperature is increased.

• The gas is moved to a larger container.

A temperature of -25 degrees Celsius is equivalent to

• 248 K

• 25 K

• -25 K

• 298 K

How does the gas propellant move when an aerosol can is used?

• from a region of high pressure to a region of lower pressure

• from a region of high pressure to a region of equally high pressure

• from a region of low pressure to a region of higher pressure

• from a region of low pressure to a region of equally low pressure
