o
If the reverse is true , heat is absorbed and the reaction is endothermic . Example- While melting the ice you provide energy to the ice to increase its temperature and change its phase to water , so it is a endothermic process .
Electrical Energy : The flow of electrical current causes bulbs to glow , fans to rotate and bells to ring . Energy is associated with an electric current .
