Question
Three moles of a monatomic ideal gas are heated at constant pressure so that the temperature rises by 100 K. Taking R = 8.314 J/(mol·K), find the heat supplied to the gas, in joules.
✓ Verified answer: 6235.5checked by our engine — not a guess
Step-by-step solution
At constant pressure Q = n*Cp*dT with Cp = 5/2 R for a monatomic gas.
Q = 3*(2.5*8.314)*100 = 3*20.785*100 = 6235.5 J.
Final answer6235.5
