a certain diatomic gas has same specific heats as an ideal gas but slightly different equation of state PV=R(T+aT^2),a=0.001k^-1.the temp. of 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 an ideal gas. CHOOSE CORRECT STATEMENT-a. T2 =400k ,internal energy increases by 250R moleb.t2=400k,internal energy increases by 350RMOLEc. total heat absorbed in process = 450R PER MOLE d.to.heat absorbed =520RPER MOLE

tough question i think some data is missing
|
|
|
|
|
which is a good book for organic chemistry.which can help in understand the basic concepts
|
|
|
|
|
www.cbse guess.com not as good because i am in class 11 and i secured 95% cbseguess question generally don't come. cbse sample papers are good .u could do together 's science. maths -rd sharma sample paper.take care of english do evergreen samplepaper
