What is the specific heat of a diatomic gas?

The molar specific heat of a gas at constant pressure (Cp is the amount of heat required to raise the temperature of 1 mol of the gas by 1◦C at the constant pressure. Its value for monatomic ideal gas is 5R/2 and the value for diatomic ideal gas is 7R/2.

What is the molar specific heat capacity of a gas undergoing an adiabatic process?

zero
The specific heat of a gas in an adiabatic process is zero but it is infinite in an isothermal process.

How do you find the molar heat capacity of a process?

The molar heat capacity of a process as C=CV+aV, where a is a constant. Find the equation of the process in the V-T variable. Hint: The molar heat capacity of a process is the amount of the heat added to a substance to change its temperature by one unit.

What is the molar heat capacity of a diatomic gas?

Constant-volume specific heat capacity of diatomic gases (real gases) between about 200 K and 2000 K. This temperature range is not large enough to include both quantum transitions in all gases. Instead, at 200 K, all but hydrogen are fully rotationally excited, so all have at least 52R heat capacity.

What is the molar heat capacities of isothermal and adiabatic process respectively?

The molar heat capacity for an ideal gas (i) Is zero for an adiabatic process (ii) Is infinite for an isothermal process > (iii) depends only on the nature of the gas for a process in which either volume or pressure is constant (iv) Is equal to the product of the molecular weight and specific heat capacity …

Can we define specific heat capacity for an adiabatic process?

In an adiabatic process, no heat exchange is allowed; so, ΔQ = 0 and hence, s = 0. Therefore, in an adiabatic process, specific heat capacity is zero.

What is the molar heat capacity of AU S?

T4: Specific Heats and Molar Heat Capacities

How do you convert molar heat capacity to specific heat capacity?

So, the conversion factor you need, from dimension analysis, will have unit kg/mol. kg/mol is the SI unit for molar mass. Multiply the specific heat by the molar mass to get the molar specific heat. For example, the molar mass of water is ≈0.018 kg/mol.

Is specific heat capacity lower than molar heat capacity?

Since the molar heat capacity of a substance is the specific heat c times the molar mass of the substance M/N its numerical value is generally smaller than that of the specific heat.
