If a refrigerator is a heat pump that follows the first law of thermodynamics, how much heat was removed from food inside of the refrigerator if it released 300j of energy to the room?unit:

300 J.

Explanation:

The first law of thermodynamics is the law that demonstrates the conservation of energy.It states that the total energy of an isolated system can not be created or destroyed, but it may be transformed into another form.The energy released to the room is 300 J.So, according to the law of conversation of energy; the amount of heat removed from food inside of the refrigerator is 300 J.

Answer the air near the ground cools to its dew point
