Explanation:

Given that,

Thermal energy chemical change lab report

We know that,

Thermal energy :

When we rise a temperature of any substance then the molecules of substance moves fastly then the heat produced. It is called thermal energy.

Chemical change in the thermal energy  :

When we heat a substance then the thermal energy increases and the molecules of substance moves fastly. That means the chemical bonds are break in reactants due to energy.

In products, The new chemical bonds are create due to energy.

For example ; The coal is burned then produced heats water and change it into steam.

Hence, This is required answer.
