Question

how does the energy and motion of particles change as a substance is heated?

Answer 1

Answer:

When a substance is heated, its internal energy increases: the movement of its particles increases. bonds between particles break when a substance melts or evaporates, or sublimes to form a gas from a solid.

Explanation:

Answer 2

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.
