PV = nRT ; R = 0.0821 L atm / mol K ; When will a 0.50 mole sample of helium occupy a volume of 11.2 liters?
273 K and 1.00 atm
volume decreases
800 mm Hg
air molecules speed up and collide with the tire walls more often.
0 K
150 deg C
The gas is placed under increasing pressure
moving randomly
Under what circumstance might a gas decrease in volume when heated?
273 K and 1.00 atm
volume decreases
800 mm Hg
air molecules speed up and collide with the tire walls more often.

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the
273 K and 1.00 atm
volume decreases
800 mm Hg
air molecules speed up and collide with the tire walls more often.
