SP40 and SP41
Consider the process AB in the TS diagram for two moles of SO3 with all degrees of freedom active. Calculate the change in internal energy of the gas, the heat input to the gas, and the work done by the gas in this process. A monatomic ideal gas of n moles at initial temperature To expands from Vo to 2Vo by the five processes indicated. Which process is a) isothermal, b) isobaric, c) adiabatic? Show calculations verifying these assignments where necessary, d) Calculate the change in entropy for each case4eaving answers in terms of n, R.Explanation / Answer
change in internal energy = 1000*100 = 100000 J
change in heat energy of the gas = 0.5*1000*100 + (1000*100) = 150000 J
from thermodynamics first law
dQ = dU+dW
work done dW = 150000-100000 = 50000 J
