What happens to the molecules of a substance when heat is added to it?

When you heat molecule you give them energy in form of motion.
Lets take CO2 molecule. When you heat it its velocity increases. Particles start flying faster. Second thing that happens is that bonds O-C-O starts vibrate more rapidly and stronger (at some point thous vibrations can torn apart molecule)
So two things happen to molecule when you heat them:
- You increase theyr velocity
- You increase vibration of bonds
the molecules start moving faster.

What is the separation of particles as heat is added which causes an increase in the size of the substance?
Whenever heat is added to the system, we increase the average kinetic energy of molecules. Increasing the K.E. of molecules cause the molecules to move further apart and collide back even more violently. This can cause size of the substance to increase.
What happens to molecules from which heat is removed?
The molecules move slower when heat is removed.
What do you call heat that is added or removed from a substance but does not change the state of the substance sensible heat latent heat super heat or radiation heat?
Latent Heat.
The molecules of any substance are what to each other?
The molecules of any substance are attracted together. Heat causes the molecules of a solid to separate from each other, making the solid become a liquid.
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
What happens to the molecules of a substance when it is melted?
the molecules vibrate, faster and faster as the heat increases then they become disordered
What happens to the volume when heat is added?
When a substance is heated it's volume will increase.

Why may the temperature of a substance change when energy is added?
Thermal energy of a substance is determined by the movement of the molecules and the potential energy of the arrangement of molecules. Heat transfer will stop when thermal equilibrium is reached. It depends upon the substance how long that takes.
What happens to the atoms or molecules of a substance when it boils?
the atoms and molecules will vibrate, causing the substance to heat up (friction causes heat, the molecules and atoms will rub together, causing friction). I hope this helped!!!!!n_n when a substance reaches its boiling point naturally the intermolecular force becomes weak and the substance gets converted from one form to another..
If heat is removed from a substance how will atoms behave?
Kinetic theory of matter: All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. ... They contract when they lose their heat.
What happens to the particles of a substance when energy is added to it?
If they are in a restricted space such as a pop can. The molecules begin bouncing off the wall. This in turn is creating heat and pressure energy. If the heat or pressure become to unstable the can simply explode. This is due to the fact of the limited room the molecules or particles can go. Now if the substance is non aqueous (without water, solid or powder) if you heat it to a certain point you could change the chemical structure of the chemical.
Is this true or false adding heat to a substance makes its molecules move quickly?
adding heat to a substance makes its molecules to move quickly
What happens when water molecules when heat is added to water molecules?
When heat is added to the water, the molecules move faster. When the water reaches the boiling point (100 Degree Celsius), the water molecules at the surface of the water would break apart with the other molecules and escape (evaporate). When they evaporate, the water molecules changes state and becomes water vapour.
What happens to molecules from which heat is removed?
The molecules move slower when heat is removed.
The particles of a substance will move faster if what is added on to them?
If heat is added to it.
