Change in internal energy is 200J.
What do you mean by internal energy?
- Internal energy, in thermodynamics, the property or state function that defines the energy of a substance in the absence of effects due to capillarity and external electric, magnetic, and other fields.
What is internal energy formula?
- The Change in Internal Energy Formula is: ΔU = Q + W.
- Here, U = the total change in internal energy within the system. Q = the heat exchanged between a system and its surroundings (outside the system).
We know that,
ΔE=Q+W
=600+(−400)
=200J.
Hence, Internal energy changes by 200J.
