Gas Laws Version A

If a gas is heated, how would you expect the gas particles to move differently?

• If a gas is heated the particles (atoms) would being to move slower

• If a gas is heated the particles (atoms) would being to move faster

• If a gas changes temperature the particle speed is unaffected

If the temperature of a gas increased, how would you predict the volume to be affected?

• The volume would increase

• the volume would decrease

• the volume would remain constant

When a sealed container that cannot change shape or size is heated, what happens to the pressure of the gas inside?

• the pressure decreases

• the pressure increases

• pressure is unaffected by temperature

Power (p), work (w), and time (t) are all related. If the amount of work done in 5 sec is more, than this means the power is more. If the amount of work done in 5 sec is less this means the power is less.

In summary:

If work increases, power increases if time remains the same

If work decreases, power decreases if time remains the same.

Which equation best represents this relationship? 

A balloon that is 100.2 L at 21 °C and 0.981 atm is released and just barely clears the top of Mount Crumpet in British Columbia. If the final volume of the balloon is 144.5 L at a temperature of 5.2 °C, what is the pressure experienced by the balloon as it clears Mount Crumpet?

At STP, how many moles are in 10 L NaO₃?

Suppose 1 mole = 15.5L.

Nitrous oxide (N₂O) is used as an anesthetic. The pressure on 2.50L of N₂O changes from 105 kPa to 40.5kPa. If the temperature does not change, what will the new volume be?
