Molecules of a substance are in constant motion. Whether you have a solid, liquid, or gas, the particles are moving (but the speed and amount they move differs). Particles of a solid move the least (they basically vibrate), particles of a liquid can flow around one another, and particles of a gas have a lot of space between them because they move in random, constant motions.

The smallest part of a molecule is what?
a molecule is the smallest part of a substance i hoped i answered your question
What makes a material a pure substance?
If all of the molecules of the substance are the same molecule
Can a molecule also be an elemental substance?
Yes
What will happen when you finally divide a single molecule of salt?
Still salt because a molecule is the smalllest possible amount of any substance that is still that substance.
Is ammonia a mixture or pure substance in chemistry?
Ammonia is pure substance. It is a molecule with formula NH(3).
Is the average amount of energy of motion in the molecule of a substance?
Heat/Temperature
What is relationship of the temperature to the movement of a molecules of a substance in the solution?
Typically the motion of a molecule in solution is proportional to the temperature; higher temperature means increased motion of the molecules.
Molecules in a substance slow down when a substance is?
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So when temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
The smallest part of a substance that still has the characteristics of that substance is a what?
The smallest part of a substance is a molecule. A molecule can be a compound of different elements or be comprised of a single element.
The smallest part of a molecule is what?
a molecule is the smallest part of a substance i hoped i answered your question
What does a molecule combine with to make a pure substance?
Nothing. A molecule is a pure substance if it is of one element.
What chemical substance is formed when the Ohs and H's are joined?
This substance is water.
Average amount of energy in motion in the molecules of a substance?
The average amount of energy in the motion of the molecules of a substance is the temperature of that substance. Heat is simply random motion on a sub-microscopic scale.
What is the smallest substance?
A single molecule of hydrogen is the smallest substance. It consists of jut two protons and two electrons.
What is the smallest substance in a solution in chemistry?
This is a molecule of solute or a molecule of solvent.
Is a pure substance a molecule?
yes
What is the smallest particle of a stubstance that has all the properties of the substance?
It is a molecule of the substance.
