Question

F23 > A system gains 632 kJ of heat, resulting in a change in internal energy of the system equal to +191 kJ. How much work is done? Choose the correct statement. O Work was done by the system. Work was done on the system.

Answer 1

from the very basic thermodynamics heat absorbed by the system is +ve so in the formula q is +ve as heat is absorbed and from there we get work W as -ve which shows work is done by the system. SEE IMAGE BELOW

Date : From yeuy basic - AU = qtw thermodynamics. 7 AU +191 KJ 1 q 5 632 kJ 80 o 191 632th

so THE WORK IS DONE BY THE SYSTEM
