Question

7. If a gas is compressed adiabatically
(1) The internal energy of the gas increases
(2) Internal energy of the gas decreases
(3) Internal energy of the gas does not change
(4) Work done by the gas is positive 7​

Answer 1

Answer:

2

Explanation:

god bless u good night

Answer 2

First low of Thermodynamics -

dQ=dU+dW

dW=150

dQ=0  (adiabatic)

dU=dQ−dW

=−150

change in  internal energy =∣dU∣=150J
