Heat increases the energy of in matter. This causes the movement of the particles making up the matter to speed up. The changes of state occur depending on the speed of the particles.
That's the heat of fusion.
Usually in the form of increased or decreased kinetic energy of the molecules and added or reduced inter-molecular potential energy. Which way it goes depends on the direction of change in state.
The heat of fusion of a substance is the energy required to change a unit mass of the substance from a solid to a liquid state at its melting point. It is measured during the phase transition process when the substance absorbs heat energy to break the intermolecular forces holding its particles together in the solid state.
Usually in the form of increased or decreased kinetic energy of the molecules and added or reduced inter-molecular potential energy. Which way it goes depends on the direction of change in state.
the heat which is absorbed by a substance for changing solid into liquid state by keeping temperature constant is called latent heat of fusion while the heat which is evolved during phase change of liquid to vapour state at constant temperature is called latent heat of vapourization
heat is produced
Yes there must be achange;but heat is required to change liquid state into gaseous state.
During the state change, it's kinetic energy stays constant as well as it's heat. But potential energy is the one to rise.
During the time of change of state,the heat or temperature is used to increase the potential energy and there by change of state.This time there will be no change in temperature.
During a change of state, such as melting or boiling, heat is either absorbed or released. When a substance changes from a solid to a liquid or from a liquid to a gas, heat is absorbed to break the intermolecular forces holding the molecules together. Conversely, when a substance changes from a gas to a liquid or from a liquid to a solid, heat is released as the intermolecular forces are strengthened.
the chemicals reacts faster
latent heat
When heat is removed from water, it undergoes a change of state from a gas (water vapor) to a liquid (water). This process is known as condensation.
During a change of state, energy is either absorbed or released as heat. This is because the particles in a substance need energy to break their bonds and move into a new arrangement. A change of state is a physical change because it does not involve a change in the chemical composition of the substance, only its physical properties.
A change of state is when a substance shifts from solid, liquid or gas to another state. This happens when heat is removed or added.
During a change of state, such as melting or boiling, the temperature generally remains constant. The energy added or removed during the phase change is used to break or form intermolecular forces, rather than changing the kinetic energy of the particles to alter temperature. Once the change of state is complete, the temperature will then either increase or decrease again depending on whether heat is added or removed.
The temperature* remains unchanged. * The heat (energy) content changes.
