Well... if it's NOT water ice, or other material that contracts upon heating...
...then the substance (solid or liquid) typically expands, since the particles move faster, loosening whatever interactions they had before to form whatever new interactions, if applicable.
Often, those new interactions are weaker than the older ones, so the particles are on average farther apart, i.e. the volume is larger.
If it's a gas, it just moves apart without exception, expanding.
Knowing that the density
#D = m/V# ,
where
