✅ The correct answer is option C.
The heat energy stored in the gas and used for raising the temperature of the gas is known as
external energy
internal energy
kinetic energy
molecular energy
✅ The correct answer is option B.
The entropy of water at 0°C is assumed to be
1
0
-1
10
✅ The correct answer is option B.
The general gas energy equation is (where Q1 – 2 = Heat supplied, dU = Change in internal energy, and W1 – 2 = Work done in heat units)
Q1 – 2 = dU + W1 – 2
Q1 – 2 = dU – W1 – 2
Q1 – 2 = dU/W1 – 2
Q1 – 2 = dU x W1 – 2
