1. The problem statement, all variables and given/known data The figure shows a thermodynamic process followed by 1.80×10−2 mol of hydrogen. How much work is done on the gas? By how much does the thermal energy of the gas change? How much heat energy is transferred to the gas? The attempt at a solution I thought the work done to gas should be negative the area underneath the curve, which is W= [(300-100)*0.001L * (4-1)atm] = (3 atm * 0.2L)/2 = 0.3 L*atm = 0.3*101.3 J = 30.39 J apparently that is neither here nor there Also, the thermal energy of the gas change would be the same as the amount of work done on the gas plus heat energy transferred to the gas, is that correct? Pleeeeeease hep, I am so confused.
