the density of a solid ___ when it is heat
The density of a solid generally decreases when it is heated. This is because heating a solid typically causes its particles to gain energy and move more vigorously, leading to an expansion of the material. As the volume increases while the mass remains constant, the density (which is mass divided by volume) decreases. However, there are exceptions to this general trend, such as in the case of certain materials like water, which behaves differently when heated
