Question

A list of changes is shown. Temperature decreases Intermolecular bonds become weaker Melting Intermolecular bonds become stronger Temperature remains constant Temperature increases Vibration of molecules slows down Molecules vibrate faster Which of the above changes would be accompanied by an increase of the kinetic energy of particles in a solid? (4 points)

Answer 1

B, C, F, and H

Step-by-step explanation:

These are all things that happen in the increase of the kinetic energy of particles in a solid.

B. Intermolecular bonds become weaker

C. Melting

F. Temperature increases

H. Molecules vibrate faster

Also, just took the test and got it right.

Answer 2

Intermolecular bonds become weaker

Melting

Temperature increases

Molecules vibrate faster

Step-by-step explanation:

In the solid phase, intermolecular forces are found to be strongest. However, as the temperature is increased, the molecules of the solid begin to vibrate faster and intermolecular forces between them begin to weaken.

As intermolecular forces of a substance become weaker, the substance melts. The molecules in the liquid state possesses greater kinetic energy than the molecules in the solid state.

Hence the the answer above.
