MCQ
When heat in given to a gas in an isobaric process, then
  • A
    The work is done by the gas
  • B
    Internal energy of the gas increases
  • ✓
    Both $ (a)$ and $(b)$
  • D
    None from $(a)$ and $(b)$
✓

Answer

Correct option: C.
Both $ (a)$ and $(b)$
c
(c)When heat is supplied at constant pressure, a part of it goes in the expansion of gas and remaining part is used to increase the temperature of the gas which in turn increases the internal energy.
