Question

what happens to the change in internal energy of a gas during

1, adiabatic expansion

2. isothermal expansion

Answer 1

1. In adiabatic expansion loss of heat is zero. And we know that
change in internal energy = heat + work done
Since heat lost is zero therefore change in internal energy is equal. to work done.

2. Incase of isothermal expansion temperature remains constant therefore change in internal energy is also constant.

Answer 2

Answer:

answer is above

internal energy of a gas during

1, adiabatic expansion

2. isothermal expansion
