Question

Given 1 mol of an ideal gas, in a state charachterized by Pa,Va , a change occurs so that the final pressure and volume are equal to Pb, VB, where Vb > Va. Which of these is true?

a) the heat supplied to the gas during the process is completly determined by Pa, Va, Pb, and Vb

b)the change in internal energy of the gas during the process is completly determined by the values Pa, Va, Pb, and Vb

c) the work done by the gas during the process is completly determined by the values Pa, Va, Pb, and Vb

d) All three are true

e) None of these is true

Explanation / Answer

b)the change in internal energy of the gas during the process is completly determined by the values Pa, Va, Pb, and Vb

For other calculations we need to know polytropic coeffienct of the process
