The change in internal energy of the system is given by the equation:
ΔU = Q - W
Where:
ΔU = Change in internal energy
Q = Heat absorbed by the system
W = Work done by the system
Given:
Q = 140J
W = -85J (negative because work is done on the surroundings)
ΔU = 140J - (-85J)
ΔU = 140J + 85J
ΔU = 225J
Therefore, the change in internal energy of the system is 225J.
Calculate the change in the internal energy of the system for a process in which the system absorbs 140J of heat from the surrounding and does 85J of work on the surrounding.
