Can someone me with these. i don't understand any of it.

1. electrical energy: electrical energy that is caused by moving electrons

2. coolant: a mixture of antifreeze and water that removes excess heat from an internal engine

3. electric compressor: a device that acts as a pump, circulating refrigerant throughout the refrigerator 

4. the inside of the fridge and the food becomes colder

5. the coolants becomes a hot, high-pressure gas 

6. as coolant transfers thermal energy to the air outside, it turns back into a liquid
