Which heat depends on the direction of current?

Molar specific heat at constant pressure of oxygen is

Match the following.

The process in which the heat is not transferred from one state to another, is:

The pressure and density of a diatomic gas$$\left ( \gamma =\dfrac{7}{5} \right )$$ change adiabatically from $$(P_1,\rho_1)$$ to $$(P_2,\rho_2)$$. If $$\dfrac{\rho _{2}}{\rho _{1}}=32 ,$$  then  $$\dfrac{P _{2}}{P _{1}}$$ should be

Heat is absorbed by a body, but its temperature does not increase. Which of the following statement explains the phenomena?

The adiabatic and isothermal elasticities $$B_\phi $$ and $$B_\theta $$ are related as : 

Consider the following two statements and choose the correct answer :
A) If heat is added to a system its temperature must always increase
B) If positive work is done by a system in thermodynamic process its volume must increase.

A fixed amount of dry air at temperature of $$27^{o}C$$ is compressed to $$\cfrac{1}{9}th$$ of original volume. Its final temperature is $$\left ( \gamma =1.5 \right )$$

An isothermal process is :
