Asked by Jessica

The air within a piston equipped with a cylinder absorbs 555 J of heat and expands from an initial volume of 0.12 L to a final volume of 0.87 L against an external pressure of 1.0 atm.

What is the change in internal energy of the air within the piston in Joules?

delta E = q + w
w = -p*delta v = -p*(V2-V1)
