Question

1. What is the effect of heating and cooling on some materials?
​

Answer 1

Answer:

If ice is warmed enough, it can change to liquid water. Heating a substance makes the molecules move faster. Cooling a substance makes the molecules move slower.

Cooling: If ice is warmed enough, it can change to liquid water. Heating a substance makes the molecules move faster. Cooling a substance makes the molecules move slower.

Heating: When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
