What is the work done by a system when it absorbs 47 J of heat and gains 12 J of energy? How much heat is released by a system when 45 J of work is done on it to decrease its energy to 23 J? For a constant-pressure expansion of a gas, the work done by the system (-w) is equal to the pressure P multiplied by the change in volume (ΔV) of a gas. Calculate the work done by the gas when its volume expands from 3.0 L to 8.0 L under atmospheric pressure. How much heat did it absorb if its energy did not change? Note: 1L atm = 101.325 J
