A piston expands against 1.00atm of pressure, from 11.2L to 29.1L. This is done without any transfer of heat.
a) calculate the change in energy of the systemb) calculate the change in energy for the above change, and in addition, the system absorbs 1,037J of heat from its surroundings
ME AYUDA POR FAVOR.
Just kidding! I figured it out. If anybody needs it:
ΔE = -PΔV
ΔE = -1atm(29.1L - 11.2L)
ΔE = -17.9 Liters(atm)
-17.9 Liters(atm) x 101.3 Liters(atm) / 1J = 1.813kJ
1.813kJ + 1.037kJ = 2.85kJ
