JEE PYQ: Thermodynamics Question 8
Question 8 - 2020 (04 Sep Shift 1)
For one mole of an ideal gas, which of these statements must be true?
(a) U and H each depends only on temperature (b) Compressibility factor $z$ is not equal to 1 (c) $C_{P,m} - C_{V,m} = R$ (d) $dU = C_V dT$ for any process
(1) (a) and (c)
(2) (b), (c) and (d)
(3) (c) and (d)
(4) (a), (c) and (d)
Show Answer
Answer: (4)
Solution
For ideal gas: (a) U and H are functions of temperature only. (b) Compressibility factor for an ideal gas is 1 (false statement). (c) $C_P - C_V = R$ (true). (d) $dU = C_V dT$ for all processes (true).
