MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Properties that depend on the amount of matter present in the system are known as extensive properties. Properties whose values depend on the specific path taken to go from the initial state to the final state are known as path functions. Free energy, enthalpy, and entropy are state functions, meaning their values depend only on the initial and final states of the system and are independent of the path followed. Heat is a path function because the amount of heat exchanged depends on the process or path taken. It also depends on the amount of matter (extensive in nature), as the heat required to change the state of a system is proportional to its mass or number of moles (q = mc T). Answer: Heat
