Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During an energy transfer process, 1000 J of heat are removed from a gas while 100 J of work is done by the gas. What is the change in internal energy of the gas?
A
+1100 J
B
+900 J
C
-900 J
D
-1100 J
Explanation: 

Detailed explanation-1: -Answer and Explanation: We need to compute the changes in the internal energy of the given system. Hence, the changes in the internal energy of the given system are 400 Joules.

Detailed explanation-2: -900 joules of heat are added to a system and 200 joules of work are done on the system. What is AE? expands against a constant pressure of 1.0 atm. The change in internal energy is 5.8 x 10 J.

Detailed explanation-3: -Hence the change in internal enrgy is −10J.
