A certain diatomic gas has the same specific heats as an ideal gas but a slightly different equation of state : PV =R(T + alphaT^(2)), alpha = 0.001 K^(-1).The temperature of the gas is raised from T_(1) = 300K to T_(2)at constant pressure. It is found that work done on the gas is 70% higher than what would be on an ideal gas. Choose the correct statement(s)

Answer»

`T_(2) = 400 K`,internal ENERGY increases by 250 R per MOLE.
`T_(2) = 400 ` K, internal energy increases by 350 Rper mole
Total heat absorbed in the process is 450 R per mole.
Total heat absorbed in the process is 520 R per mole.
