Question

1) Define Insulators.Give one example
ii)Define heat energy.
iii) How do changes in temperature break rocks?​

Answer 1

A conductor is that which easily allows the passage of current through it. Example: Aluminium or any metal. An insulator is that which does not allow the passage of current through it.

The definition of heat energy is the transfer of energy from one thing to another by kinetic energy, usually causing a higher temperature.
