The energy associated with the random motion of molecules or atoms within a substance is?
Thermal energy
how the addition of thermal energy affects particle motion?
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 determine the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
What motion of energy does the motion of atoms and molecules produce?
heat...
What happens when particles are warm?

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.
What happens to the molecular motion of a liquid as it freezes?
As the temperature of a liquid substance lowers, the molecules and atoms making up the substance slow down their movement. The also pack closer together, making the substance more rigid, turning it into a solid.
The energy associated with the random motion of molecules or atoms within a substance is?
Thermal energy
What is thermal energy?
related to the motion of molecules
Explain chemical changes in terms of the structure and motion of atoms and molecules?
a chemical change destroys the old atoms and molecules to make completely new ones and a completely new substance.
Is the average amount of energy of motion in the particles of substance?
The average amount of energy of motion (also known as kinetic energy) in the particles of a substance (atoms and molecules) is measured by the temperature of that substance. More energy will produce a higher temperature.

What is the meaning of the term temperature?
The degree of hotness of a body, substance, or medium; a physical property related to the average kinetic energy of the atoms or molecules of a substance.
Does temperature have atoms and molecules?
Temperature itself is not a substance and is not composed of atoms or molecules. However it is a measure of the activity of the atoms or molecules of the substance you are measuring the temperature of. That is, the warmer a substance becomes the more active are its atoms and the higher its temperature.
What are the likes and differences of atoms and molecules?
atoms have one substance, when molecules have many. They bioth have ele torn
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
How are atoms related to molecules in a sample of a compound?
atoms are made of molecules and that is why they are related !
