When an ideal gas is compressed isotherm...

When an ideal gas is compressed isothermally then its pressure increase because:

A

its potential energy decreases

B

its kinetic energy increases and molecules move apart

C

its number of collisions per unitl area with walls of container increases

D

molecules energy increases

Text Solution

Verified by Experts

The correct Answer is:
C
For isothermal, `PV =` constant, `P alpha (1)/(V)`. As area decreases
`:.` number of collision per unit area increases

  • When an ideal gas is compressed adiabatically , its temperature rises the molecules on the average have more energy than before. The kinetic energy increases,

    A
    because of collision with moving parts of the wall only.
    B
    because of collisionws with the entire wall.
    C
    because the molecules gets accelerated in their motion inside the volume.
    D
    because the redistribution of energy amongst the molecules.
