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.
What else can I help you with?
Can a molecule also be an elemental substance?
Yes, a molecule can be an elemental substance if it is made up of atoms of the same element bonded together. For example, O2 is a molecule of the elemental substance oxygen, composed of two oxygen atoms bonded together.
The smallest part of a molecule is what?
The smallest part of a molecule is an atom. Atoms are the basic units of matter and are composed of protons, neutrons, and electrons.
What are two words that mean a substance made of atoms that are bonded together?
Molecule and compound are two words that mean a substance made of atoms that are bonded together.
When haemoglobin molecule combines with oxygen the substance is called?
oxyhemoglobin
What is the difference beteween molecule and compound?
A molecule is the smallest unit of a substance that retains all the properties of that substance, while a compound is a substance made up of two or more different elements chemically bonded together. All compounds are molecules, but not all molecules are compounds.
Is the average amount of energy of motion in the molecule of a substance?
Heat/Temperature
The smallest part of a substance that still has the characteristics of that substance is a what?
The smallest part of a substance that still has the characteristics of that substance is called a molecule.
What is the total energy of motion in a molecule?
The total energy of motion in a molecule is referred to as its kinetic energy. This includes the energy associated with the molecule's translational, rotational, and vibrational motion. Temperature is a measure of the average kinetic energy of molecules in a substance.
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.
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 any substance that has all the properties of that substance?
Molecule
What makes a material a substance?
If all of the molecules of the substance are the same molecule
What is the smallest particle of a stubstance that has all the properties of the substance?
It is a molecule of the substance.
Does the amount of heat in a substance depend on the motion of the molecules?
Yes, the amount of heat in a substance is related to the motion of its molecules. Heat is a form of energy that corresponds to the motion of molecules within a substance. The more heat a substance has, the faster its molecules move.
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.
