Question

Which of the following is true of an adiabatic process?

A. -ΔU = W
B. Heat is constant.
C. Volume is constant.
D. Q = 0

Answer 1

The answers are A,B,and D. APEX

Answer 2

Adiabatic process is that process in which heat of a closed system will remain conserved or we can say that system can not exchange its thermal energy from its surrounding

So here from 1st law of thermodynamics we can say

`\Delta Q = \Delta U + W`

since we know that

`\Delta Q = 0`

so we will have

`0 = \Delta U + W`

so we have

`-\Delta U = W`

so here correct answers are

A. -ΔU = W

B. Heat is constant.
