1.	A system gives out 20 J of heat and also does 40 j of work . What is the internal energy changes
Answer» Answer: 60 J Explanation: Given : Δ W = 20 J Δ Q = 20 J We are asked for for Δ U We have : Δ U = Δ Q + Δ W Δ U = 20 + 40 J Δ U = 60 J Therefore , change in internal ENERGY of the system is 60 J.

A system gives out 20 J of heat and also does 40 j of work . What is the internal energy changes

Answer»

60 J

Given :

Δ W = 20 J

Δ Q = 20 J

We are asked for for Δ U

We have :

Δ U = Δ Q + Δ W

Δ U = 20 + 40 J

Δ U = 60 J
