Type of energy that depends on how fast the molecules in a substance are moving?
Kinetic energy is the type of energy that depends on how fast the molecules in a substance are moving.
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
How are states of matter and changes in energy related?
When thermal energy is added or removed, the state of matter changes to another eg. solid becomes liquid and liquid becomes gas.
The addition or loss of thermal energy changes the arrangement of the particles during what?
a change of state
How is heat different from thermal energy?
There is no particular difference between heat and thermal energy. Heat is a form of thermal energy. Since thermal energy is energy from heat, heat and thermal energy are basically the same thing.
What happens to a substance as its thermal energy increases?
As thermal energy increases, the substance's particles move faster, leading to an increase in temperature. Eventually, the substance may undergo a phase change (e.g., melting or boiling) or undergo chemical reactions if the increase in energy is significant enough.
What does a substance gain or lose when its temperature changes?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
When a substance is what it gains thermal energy?
When a substance gains thermal energy, its temperature increases as the particles within the substance move faster and have greater kinetic energy. This increased thermal energy can lead to changes in the physical state of the substance, such as melting or boiling if enough energy is absorbed.
What happens to the thermal energy of a substance as its temperature increases?
As the temperature of a substance increases, its thermal energy also increases. This leads to greater kinetic energy of the particles within the substance, causing them to move faster and creating more thermal energy.
What type of energy is related to changes in temperature?
Thermal energy is related to changes in temperature. When the temperature of a substance increases, its particles move faster, increasing the thermal energy of the system.
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.
Is Freezing a Thermal Energy Added?
Freezing is the process where a substance changes from a liquid to a solid by extracting heat energy. So, freezing actually involves the removal of thermal energy from a substance rather than adding thermal energy.
What happens to thermal energy if the molicules speed up?
If molecules speed up, they gain kinetic energy which increases the thermal energy of the substance. This causes the temperature of the substance to rise since thermal energy is directly related to the average kinetic energy of the molecules.
Does thermal energy depend on amount of substance?
Yes, thermal energy does depend on the amount of substance. The more mass a substance has, the more thermal energy it can store. This is because thermal energy is related to the internal energy of a substance, which increases with the amount of substance present.
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 freezing thermal energy in science?
Freezing is the process by which a substance changes from a liquid state to a solid state by removing thermal energy. This removal of thermal energy causes the particles in the substance to slow down and come closer together, forming a solid structure.
