What happens when a piston is used to decrease the volume of a contained gas group of answer choices?
In. What happens when a piston is used to decrease the volume of a contained gas? Gas particles become compressed. The volume of a gas is directly proportional to its temperature in kelvins.
What does R mean in ideal gas law?
The factor “R” in the ideal gas law equation is known as the “gas constant”. R = PV. nT. The pressure times the volume of a gas divided by the number of moles and temperature of the gas is always equal to a constant number.
What is ideal gas Byjus?
The ideal gas law, also known as the general gas equation is an equation of state of a hypothetical ideal gas. The ideal gas law states that the product of the pressure and the volume of one gram molecule of an ideal gas is equal to the product of the absolute temperature of the gas and the universal gas constant.
What is the ideal gas constant for oxygen?

| Nitrogen | N2 | 0.2968 |
| Octane | C8H18 | 0.0729 |
| Oxygen | O2 | 0.2598 |
What is the value of gas constant R?
| Constant | Value | Units |
|---|---|---|
| R | 0.08206 | L·atm/K·mol |
| R | 8.3145 | J/K·mol |
| R | 1.9872 | cal/K·mol |
| Vm | 22.414 | L/mol |
Why the value of CP is greater than CV?
Cp is greater than the molar specific heat at constant volume Cv because energy must now be supplied not only to raise the temperature of the gas but also for the gas to do work. More heat would be required at constant pressure to cause the same temperature rise and Cp will be greater than Cv.
