JEE Main 2025 — Thermodynamics (C) Question with Solution
JEE Main 2025 (3 Apr Shift 2)
Question
Given below are two statements :
Statement I : When a system containing ice in equilibrium with water (liquid) is heated, heat is absorbed by the system and there is no change in the temperature of the system until whole ice gets melted.
Statement II : At melting point of ice, there is absorption of heat in order to overcome intermolecular forces of attraction within the molecules of water in ice and kinetic energy of molecules is not increased at melting point.
In the light of the above statements, choose the correct answer from the options given below:

Correct answer
CBoth Statement I and Statement II are true
Step-by-step explanation
At melting point when ice melts, supplied heat is utilised to overcome intermolecular attraction within the molecules so temperature remain constant.
