Electrical energy goes into a refrigerator and thermal energy comes out.

1. It's true that the food that comes out of the fridge contains energy (chemical).
2. The light that comes on when you open the door also emits light energy (electro-magnetic radiation).
3.I think the answer you're looking for is thermal (heat) energy.
A gas is compressed to liquid form by a pump.
The liquid is circulated inside the fridge.
Heat warms the liquid (turning it back to a gas)
The warm gas is then circulated through the pipes at the back of the fridge (heat is radiated allowing the gas to cool)
The gas is compressed to a liquid again and the cycle repeats....
Hope that's OK?
PS 1 and 2 were just for the smarties.

Heat energy (from your food) becomes latent heat of vaporisation (of the freon) which transforms into the kinetic energy of the molecules (of freon).
Freon then moves towards a compressor and is compressed back into a liquid. The kinetic energy is hence transformed into heat energy once again and escapes from the back of the fridge.

heat is radiated out.. Electric energey is firast used to create kinetic energy in compressor which converts Kinetic energy to cooling & compression of gases which then gets hot by cooling the inside of fridge...

Thermal energy? This really isn't chemistry, it's physics.
