Solving 1.5 Moles Monatomic Ideal Gas at 314K - No Calc

[cdymdcool]

1. 1.5 moles of a monatomic ideal gas is enclosed at 314K. THe initial volume of the gas is 3m^3. The gas is comperssed isothermally to a final volume of 1m^3. How much heat is removed from the gas.



So deltaU=0, Q=-W, So we have to know the area under the P-V curve, but how can we get the solution without calculus?

We can't. Algebra-based textbooks just provide the appropriate equation and justify it by saying that it can obtained by using calculus.
