When a body is heated, it expands in terms of area, length & temperature and volume rises. In a solid, molecules may only have thermal agitation. As temperature of a object enhances, the vibrations of molecules will goes fast and because of this the rate of collision between neighboring molecules increases, it makes a thermal stress in the body and because of this the intermolecular separation enhances which results in thermal expansion of objec.
