What statement represents the first law of thermodynamics?

AWhen heat is transferred from one body to another, the internal energy given up by the first body must be greater than the internal energy taken up by the second body.
BWhen heat is transferred from one body to another, there is no mathematical relationship between the internal energy given up by the first body and the internal energy taken up by the second body.
CWhen heat is transferred from one body to another, the internal energy given up by the first body must be less than the internal energy taken up by the second body.
DWhen heat is transferred from one body to another, the internal energy given up by the first body must be equal to the internal energy taken up by the second body.
AI Explanation

The correct answer is D) When heat is transferred from one body to another, the internal energy given up by the first body must be equal to the internal energy taken up by the second body. This statement represents the first law of thermodynamics, which states that energy can be converted from one form to another, but it cannot be created or destroyed. When heat is transferred from one body to another, the internal energy given up by the first body must be equal to the internal energy taken up by the second body, as energy is conserved in this process. The other options are incorrect because they do not accurately represent the first law of thermodynamics. Option A) suggests that the internal energy given up by the first body must be greater than the internal energy taken up by the second body, which is not the case. Options B) and C) do not correctly describe the relationship between the internal energies of the two bodies.
