Mass is a basic properties of the body. The mass of a body does not change with a physical reaction, such as expansion. Neither does its weight. The only change is probably just its volume.
The mass of the body will change under a nuclear reaction or chemical reaction, because the body has changed into a different entity -- it becomes a different object or objects. Its nature has changed.

When a substance expands what happens to its mass?
When a substance expands, its mass remains constant, as mass is a measure of the amount of matter in an object and does not change with volume. However, the density of the substance decreases because density is defined as mass per unit volume. Thus, as the substance expands and its volume increases, the same mass is distributed over a larger volume, resulting in lower density.
