Question

What is the effect on
the molecules of matter when the temperature is varied?
​

Answer 1

Answer:

When the temperature of matter is varied it may change state.

Explanation:

Freezing: When molecules are at lower temperatures, the molecules will settle into low-energy states and move very little. This is called freezing and causes matter to turn into a solid.

Melting: When turning into a liquid, molecules are excited and in motion. However, they are not in a high-energy state like a gas. Think of this as a medium-energy state.

Boiling: When molecules are at high temperatures, they are in a high-energy state. These molecules take the form of a gas, which are free to move anywhere.

Hope this helps!

Answer 2

Answer :

• Increase in temperature causes the molecules and atoms of a substance to vibrate quicker. The distance between atoms expands as atoms vibrate faster. The state of matter of a substance is determined by the velocity and spacing of the particles. The thing grows and takes up more space as a result of enhanced molecular mobility. However, the object's mass remains constant.

• Heat causes solids, liquids, and gases to expand. When heat is removed from any substance, the molecules vibrate at a slower pace. The atoms can move closer together, causing matter to constrict. The mass remains unchanged.
