Question

What is the first law of thermodynamics?

The first law of thermodynamics states that the change in the________
of an object is equal to the difference of the_______
supplied to the system and the________
done by it.

Answer 1

Answer: The first law of thermodynamics states that the change in the internal energy of an object is equal to the difference of the net heat supplied to the system and net work done by it

Explanation: The first law of thermodynamics states that energy can not be created nor destroyed but it can be converted from one form of energy to other forms of energy, which involves the transfer of the heat, Q, of the body or work, W by the body, which combined leads gives the change in the internal energy, ΔU, of the body

Therefore;

ΔU = Q - W

Answer 2

The first law of thermodynamics states that the change in the internal energy of an object is equal to the difference of the net heat supplied to the system and net work done by it

Step-by-step explanation:
