Answer:
c. change solid to liquid.
Explanation: Heat is an energy which is present in a substance which is obtained through the transfer of temperature from a substance or material of high temperature to a substance or material of lower temperature. Heat is measured in JOULES OR KILOJOULES,
When heat is applied to a solid material it tends to cause the atomic particles of the solid to have a high kinetic energy making them to loose attachment to each other,when this particles starts to get detached their is the chance of a CHANGE OF STATE WHICH CAN BE FROM SOLID TO LIQUID OR FROM LIQUID TO GAS.
