Apentix/AP Chemistry/Unit 3: Intermolecular Forces and Properties/Question

AP Chemistrymediummcq1 pt

During melting, the temperature of a pure solid remains constant. Why?

A.Added energy breaks intermolecular attractions instead of raising temperature

B.Melting releases exactly as much heat as it absorbs

C.The solid stops absorbing heat

D.Intermolecular forces disappear

Explanation

Core Concept

At the melting point, heat input works against the IMFs holding the lattice together. Only after all the solid melts does added energy raise temperature again.

Correct Answer

AAdded energy breaks intermolecular attractions instead of raising temperature
