The internal energy of the gas increases In

A

Adiabatic expansion

B

Adiabatic compression

C

Isothermal expansion

D

Isothermal compression

Text Solution

Verified by Experts

The correct Answer is:
B

For adiabatic process -
`DeltaU = - DeltaW`
In adiabatic compression `Delta W rarr` -ve
So `Delta`U is +ve i.e. internal energy increases.

N_2 is confined in a cylindrical vessel with a movable piston exposed to open atmosphere. If 25 kcal of heat is added to it and the internal energy of the gas increases by 8 kcal, find the work done by the gas.

A cylinder containing a gas is lifted from the first floor to the second floor. What is the amount of work done on the gas? What is the amount of work done by the gas? Is the internal energy of the gas increased ? Is the tempreture of the gas increased?

There is a sample of diatomic gas in a container (whose volume is constant). The temperature of this gas was increased greatly so some molecules fell into atoms (dissociated). The pressure of the gas increased by a factor of 6 and the internal energy of the gas increased to a value of 4.4 times the original internal energy. By what factor did the temperature of the gas (measured in Kelvin) increases?
