Question

Match List -I with List -II 

List - I		List -II
a	Isothermal	i	Pressure constant
b	Isobaric	ii	Temperature constant
c	Adiabatic	iii	Volume constant
d	Isobaric	iv	Heat content is constant

Choose the correct answer from the options given below

• A. $(a) \to (i), (b) \to (iii), (c) \to (ii), (d) \to (iv)$
• B. $(a) \to (ii), (b) \to (iii), (c) \to (iv), (d) \to (i)$
• C. $(a) \to (ii), (b) \to (iv), (c) \to (iii), (d) \to (i)$
• D. $(a) \to (iii), (b) \to (ii), (c) \to (i), (d) \to (iv)$

Answer 1

The Correct Option is B

To solve this question, we need to match the given thermodynamic processes in List-I with their corresponding constant parameters in List-II. Let's analyze each process:

1. Isothermal Process:
   • An isothermal process occurs at a constant temperature. Therefore, the correct match is (a) \to (ii).
2. Isobaric Process:
   • An isobaric process is characterized by a constant pressure. Thus, the correct match is (b) \to (i).
3. Adiabatic Process:
   • In an adiabatic process, there is no heat exchange with the surroundings, meaning the heat content (or enthalpy) is constant within a closed system. So, the correct match is (c) \to (iv).
4. Isochoric Process:
   • Although not listed separately in this question, it's important to note that an isochoric process occurs at a constant volume. However, based on given options, "d" is a duplicate of "b" indicating an error in the original question—nonetheless, using context, pressure is constant, matching with available explanations.

Therefore, the correct option that follows these explanations is:

(a) \to (ii), (b) \to (iii), (c) \to (iv), (d) \to (i)
