Which of the following statement(s) is/are true ? “Internal energy of an ideal gas ………………”
(A) decreases in an isobaric process.
(B) remains constant in an isothermal process.
(C) increases in an isobaric process.
(D) decreases in an isobaric expansion.
Which of the following statement(s) is/are true ? “Internal energy of an ideal gas ………………”
(A) decreases in an isobaric process.
(B) remains constant in an isothermal process.
(C) increases in an isobaric process.
(D) decreases in an isobaric expansion.
The correct option (B) remains constant in an isothermal process.
Explanation:
In isothermal process ΔU = 0
In isobaric expansion V ∝ T so ΔU increases.
