AP Chemistryeasymcq1 pt

Which statement is part of the kinetic molecular theory of gases?

A.Collisions between gas particles are perfectly elastic
B.Gas particles attract each other strongly
C.Gas particles move in straight lines only at high pressure
D.Gas particles occupy most of the container volume

Explanation

Core Concept

KMT assumes particles are point masses whose collisions conserve total kinetic energy, so no energy is lost to attraction or deformation. This lets pressure be explained purely by collisions with walls.

Correct Answer

ACollisions between gas particles are perfectly elastic
