Think of a balloon. It is tied up. It has air inside. If you heat the balloon up, it expands but the amount of air inside the balloon stays the same. Therefore, there is less air per cubic millimetre, making it less dense.
A measure of mass per unit of volume. It is how much material a certain volume contains. ... If the volume of the object stays the same but the mass of the object increases then its density becomes greater.
The density decreases.

decrease
Explanation:
We all know, Density = Mass/ volume. When volume increases and the mass remains the same , the density will decrease considerably
