Question

one mole diatomic ideal gas undergoes ABC as shown in figure . The process BC is adiabatic . The temprature at A, B and C are 400k , 800 k and 600k respectively .

Choose the correct statement .

(a) The change in internal energy in whole process is 250R
(b) The change in internal energy in the process CA is 700R
(c) The change in internal energy in the process AB is -350R
(d) The change in internal energy in the process BC is -500R ​

Answer 1

Answer:

I think

the answer is

the change in the internal energy in the process AB is-350R(c)
