A sealed aerosol can is left in hot sunlight.
Which statement explains why the pressure of the gas inside the can increases?
The particles move faster, so they hit the walls more often and with more force
The particles move faster, so they take up more room and push the can outwards
The particles gain mass when they are heated, so each collision is harder
More particles are made as the gas is heated, so there are more collisions
