Question

give some situations in day to day life where different form of energy converted into heat?

Answer 1

Friction (Kinetic energy → Heat)
Electric heater (Electric energy → Heat)
Fire (Chemical energy → Heat and Light)
Electric lamp (Electric energy → Heat and Light)

Answer 2

According to the Law of Conservation of energy, energy is neither created not destroyed. It only get transformed from one form of energy to other.

Few examples in daily life where we observe conversion of different form of energy to heat energy:

●Electric heater - electric energy to heat energy.
● Electric stove- electric energy to heat energy.
● Light bulb- electric energy to heat and light energy.
● Friction - mechanical energy to heat energy.
● SOLAR HEATER--- SOLAR energy to heat energy.
● Electric Iron - electrical energy to heat energy.
