During adiabatic changes, `V prop 1//T^(2)`. How will pressure of the gas vary with temperature?

During an adiabatic process , the pressure of a gas is proportional to the cube of its temperature . The value of C_(I)//C_(v) for that gas is

For an adiabatic change in a gas, if P,V,T denotes pressure, volume and absolute temperature of a gas at any time and gamma is the ratio of specific heats of the gas, then which of the following equation is true?

During the adiabatic change of ideal gas, the realation between the pressure and the density will be:

In an adiabatic change, the pressure and temperature of a monoatomic gas are related with relation as P prop T^(C ) , Where C is equal to:

In an adiabatic change, the pressure P and temperature T of a diatomic gas are related by the relation P prop T^C , where C equals to :
