Characteristics gas constant of a gas is equal to _____
- Cp/Cv
- Cv/Cp
- Cp– Cv
- Cp+ Cv
Table of content
Answer: C- Cp– Cv
Characteristics gas constant of a gas is equal to Cp– Cv
Solution:
The gas constant, denoted by Ro, is a physical constant expressed in units of energy per temperature increment per mole. It is also referred to as the Ideal gas constant, the molar gas constant, or the universal gas constant.
Ideal gas equation,
PV = nRoT
Where
- P is the pressure,
- V is the volume,
- n is the number of moles of the given substance, and
- T is the temperature.
Characteristics gas constant,
PV = mRT
R =Ro/M,
Where,
- R= Characteristics gas constant,
- M = molecular weight
R= Cp– Cv
- Cp= heat capacity at constant pressure
- Cv= heat capacity at constant volume
