# Getting back to the old things #1

One mole of a mono atomic ideal gas undergoes a thermodynamic process such that $$V^3/T^2$$= constant. Then:

1. Work done by gas is 200R when temperature of gas is raised by 300K.
2. Specific heat of gas in the process is $$13R/6$$.
3. Work done by gas is 300R when temperature of gas is raised by 600K.
4. The specific heat of the gas in the process is $$21R/4$$.

Which of the above statements are true? Give the answer as the product of serial numbers of the right options. For ex. If 1 and 4 are correct the answer should be 1×4=4.
