It depends what substance you mean and to what extent it is heated. Each material has a generally different melting points, and some changes made to the materials are different. Say you mean metal was heated to melting point, it would of course melt. I just heated some grated cheese in a 1000W microwave and most of it was melted in 50 seconds, it would have completely melted given 20 more seconds. I tried the same thing a while ago with a thin porcelain plate for my beverage and withing 15 or so seconds the plate broke in half, no conatact was made to it by me or pretty much any other substance, it was the heat that had done it. Now, if you heat an egg, it cooks and that is irreversible, it will always be cooked. If you melt metal through heating it, it will be liquid metal and that is a reversible change made, for it will solidify if allowed to cool. Of course some things as well may hardly heat at all, like wood, which is an insultor of heat, it will take hours or less to heat depending on how you heat it, but mostly the wood will just heat up, and soften maybe. That is the same with plastic which I had my ready meal in, it was cooked for 10 minutes and it softened with heating but hardened once more as it was allowed to cool. Another pint is, as I have discovered, as the food gets heated some times the air under the film lid gets hot s well, and when you lift it scolding steam rises and burns your hand. I welcome anyone to correct my answer, it is poorly written and to my mental capacity it is a complicated question to answer.

What happens when heat is added to a substance?
well this isn't a specific question you see there is 2 different kind of substances ; For example:... solid : when heat is added to a solid it becomes a liquid liquid: when heat is added to a liquid it becomes a gas! for example water > if you add heat it will hot add or take away chemicals!
The transformation of matter from a liquid to a gas due to added energy?
This is called "vaporization" or "evaporation." When energy is added to a liquid, the molecules gain enough energy to overcome the forces holding them together in the liquid state, causing them to escape into the gas phase. This process occurs at the liquid's surface and is influenced by factors such as temperature, pressure, and the properties of the substance.
How does a substance change from one state of matter to another?
A substance changes from one state of matter to another by either gaining or losing energy. For example, to change from a solid to a liquid, energy is added to break the intermolecular bonds. To change from a liquid to a gas, more energy is added to overcome the forces of attraction between the molecules.
What happens to water when heat is added?
When heat is added to water, the temperature of the water increases, causing the water molecules to gain more kinetic energy and move faster. Eventually, the added heat can cause the water to reach its boiling point, at which point it will vaporize and turn into steam.
What do you call it when oxygen is added to a substance?
When Oxygen is added to a substance it is called oxidation.
When energy is added to molecules what happens to the substance?
they spread apart and move faster when energy is added.
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
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.
When freezing happens is energy added?
No, in freezing, energy is actually removed from a substance. As the temperature drops, the molecules within the substance slow down and come closer together, eventually forming a solid state. This process releases energy in the form of heat.
When heat energy is added the speed of the molecules blank?
When heat energy is added, the speed of the molecules increases. This increase in speed leads to a higher kinetic energy and results in a rise in temperature of the substance.
What is happening to a substance undergoing thermal energy?
As thermal energy is added to a substance, its temperature increases, causing its molecules to move faster and vibrate more. This can lead to changes in state, such as melting or boiling, depending on the substance and the amount of thermal energy being added.
What happens to molecules as energy is added and the temperature increases?
As energy is added and temperature increases, molecules gain kinetic energy and move more rapidly. This increase in movement can lead to stronger molecular interactions, changes in molecular configuration, and ultimately a change in the state of matter (e.g., from solid to liquid or gas).
What happens when you add heat in a substance?
When heat is added to a substance, its molecules gain energy and move faster, causing the substance to increase in temperature. This can lead to changes in physical state, such as melting or boiling, depending on the substance's properties. In some cases, chemical reactions may also occur due to the increased thermal energy.
Why does evaporation require that heat energy be added to a substance?
Evaporation requires heat energy to be added because it provides the molecules in a substance with enough kinetic energy to overcome the attractive forces holding them together. As molecules gain energy, they move faster and escape the liquid phase, transitioning into the gas phase. This process leads to evaporation.
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 velocityYou increase vibration of bondsthe molecules start moving faster.
What happens to the particles when thermal energy is added or removed?
When thermal energy is added to a substance, the particles gain kinetic energy and move faster, increasing the substance's temperature. When thermal energy is removed, the particles lose kinetic energy and slow down, causing the temperature to decrease.
What is a direct cause of a substance's temperature increase?
The direct cause of a substance's temperature increase is the input of thermal energy, typically in the form of heat. This added energy increases the kinetic energy of the substance's molecules, causing them to move faster and leading to an increase in temperature.
