Question

If KE becomes less than IF, what phase change occurs?

Answer 1

Answer: liquid to solid

Explanation: Kinetic energy is the energy possessed by an object by virtue of its motion.

Solid is the phase of matter where particles have strongest inter molecular forces and thus molecules posses no kinetic energy.

Liquid is the phase of matter where kinetic energy of the molecules is almost equal to the inter molecular forces.

Gas is the phase of matter where kinetic energy of the molecules is more than the inter molecular forces present among molecules and hence the molecules move randomly.

Thus the phase change is from liquid to solid.
