Question

heating a substance can make it expand
​

Answer 1

Answer:

Hope this helps you....!!!

Explanation:

When a material is heated, the kinetic energy of that material increases and its atoms and molecules move about more. This means that each atom will take up more space due to its movement so the material will expand. When it is cold the kinetic energy decreases, so the atoms take up less space and the material contracts.

Answer 2

Answer:

for metals it increases but for non metals it does not.
