Thermodynamics
The molar heat capacity of oxygen gas at STP is nearly 2.5 R. As the temperature is increased, it gradually increases and approaches 3.5 R. The most appropriate reason for this behaviour is that at high temperature :
The ratio of specific heat capacity to molar heat capacity of a body
Specific heat capacity(C) is the amount of heat required per unit mass to raise the temperature by 1K.
Molar heat capacity(s) is the amount of heat required per mole to raise the temperature by 1K.
Thus $$\dfrac{C}{s}=\dfrac{moles}{mass}=\dfrac{1}{M_o}$$

Figure shows a process on a gas in which pressure and volume both change.The molar heat capacity for this process is C
Two moles of an ideal gas at a temperature of $$T=273\ K$$ was isothermally expanded $$4$$ times the initial volume and then heated isochorically, so that the final pressure becomes equal to the initial pressure. The ratio of molar specific heat capacities if total amount of heat imparted to the gas equals $$Q=27.7\ kJ$$, is
Molar heat capacity is directly related to :
In an industrial process the volume of $$25.0$$ mol of a monoatomic ideal gas is reduced at a uniform rate from $$0.616\ m^3$$ to $$0.308\ m^3$$ in $$2.00\ h$$ while its temperature is increased at a uniform rate from $$27.0^oC$$ to $$450^oC$$. Through out the process, thegas passes through thermodyamic equilibrium states. What are the molar specific heat for the process? $$\displaystyle \int \dfrac {a+bx}{A+Bx}dx=\dfrac {bx}{B}+\dfrac {aB-bA}{B^2}\ln (A+Bx)$$ an indefinite integral. Suppose is replaced with a two step process that reaches the same final state. In step $$1$$, the gas volume is reduced at constant temperature, and in step $$2$$ the temperature is increased at constant volume. For this process,

Air at $$0.000^oC$$ and $$1.00$$ atm pressure has a density of $$1.29\times10^{-3} g/ cm^3$$, and the speed of sound is $$331\ m/s$$ at that temperature. Compute the ratio $$\gamma $$ of the molar specific heats of air.
A certain substance has a mass per mole of $$50.0\ mol$$. When $$314\ J$$ is added to a $$30.0\ g$$ sample, the sample's temperature rises from $$25.0^oC$$ to $$45.0^oC$$. What are the molar specific heat of this substance?
Specific heat depends on __________, ____________ and ___________.
State whether true or false : The substance with more specific heat has greater ability to store heat.
