Answer :
The change in internal energy of system is −87 J and that of environment is 87 J.
Calculation :
given,
Q = 164 j
W = 77 j
Q = W +ΔU
77 = 164 + ΔU
ΔU = 77 - 164
= - 87 j
The change in internal energy of system is −87 J and that of environment is 87 J.
In physics, energy is the quantitative property transmitted to the body or physical system, perceived in the performance of work and in the form of heat and light. Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed. The unit of measure for energy in the International System of Units (SI) is the joule (J).
