Answer:- 2.=> expands
Reason:-
As we know that air contains molecules in it and when it heated the force of attraction between the molecules is weak and kinetic energy between molecules decrease. So at that time all molecules move away from each other.
So when air is heated it expands in surrounding and goes up due to high kinetic energy and low molecular force of attraction.
