A student heats a sealed rigid can of air and says that the pressure rises because the air inside the can expands. Why is the student's explanation wrong?
The air inside the can cannot be heated because the can is sealed.
The volume of the air cannot change, so the air does not expand.
The pressure of the air falls rather than rises when it is heated.
The air molecules move more slowly, so they expand less quickly.
