What happens to atoms when you add heat to them

Asked by admin @ in Biology viewed by 271 People

The atoms and molecules that make up substances are always in motion. What happens when heat or thermal energy is added to a substance?

the particles move faster
the particle movement doesn't change
the particles move slower
the particles stop moving

Answered by admin @


Answer:

the particles move faster

Explanation:

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.
