Chemistry Question on Thermodynamics

A system has internal energy equal to E1E_1, 450 J of heat is taken out of it and 600 J of work is done on it. The final energy of the system will be

A

(E1+150)(E_1 + 150)

B

(E1+1050)(E_1 + 1050)

C

(E1150)(E_1 -150)

D

none of these

Answer

(E1+150)(E_1 + 150)

Explanation

Solution

Hint E2E1+q+w;q450J,w=600JE_2 - E_1 + q + w ; q - 450\, J, w = 600 \,J
