In a process, 701 J of heat is absorbed by a system and 394 J of work is done by the system. What is the change in internal energy for the process?

According to the first law of thermodynamics,  ∆U = q + W (i)  Where,  ∆U = change in internal energy for a process  q = heat  W = work Given,  q = + 701 J (Since...

In a process, 802 J of heat is absorbed by a system and 294 J of work is done by the system. What is the change in internal energy for the process?

ΔU = q + w  ΔU = 802 + (-294) =508J

What happens to the internal energy of the system. if work is done by the system.

ΔU Decreases. (ΔU = q - w)

What happens to the internal energy of the system. Work is done on the system.

ΔU increases. (ΔU = q + w)

Express the change in internal energy of a system when:- No work is done on the system, but ‘q’ amount of heat is taken out from the system

Δ U = - q, thermally conducting walls

Express the change in internal energy of a system when:- ‘w’ amount of work is done by the system and ‘q’ amount of heat is supplied to the system.

Δ U = q – w, closed system
