Question

give an equation for the relation between change in internal energy and pressure volume work......​

Answer 1

Pressure–Volume Work

During an expansion (Figure 12.5), an increase in volume decreases the internal pressure of a system as the system does work. ... Because pressure is constant, the work done is PΔV . Recall that the formula for work is W=Fd.

Answer 2

Answer:

During a compression, a decrease in volume increases the internal pressure of a system as work is done on the system. ... Because pressure is constant, the work done is PΔV . Recall that the formula for work is W=Fd. We can rearrange the definition of pressure, P=FA, to get an expression for force in terms of pressure.
