Change of the phase of electrical current in a circuit or of an el magnetic wave propagating in space means change of the rate of oscillations per second of the source (generator, in particular) of the oscillations. In FM (frequency modulated )radio wave transmission sounds (music, speach) are made to modulate frequency of the generator - its rate of oscillations is changing according to the changes in phase of the vibrations of sound waves in air.
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
Phase changes occur when there is a change in temperature or pressure that affects the arrangement of particles in a substance. When a substance gains or loses energy, its particles can move farther apart or closer together, leading to a change in phase (such as melting, freezing, boiling, or condensation) as the substance transitions between solid, liquid, and gas states.
Phase changes occur when a substance transitions between different states of matter, such as solid, liquid, or gas. Factors that influence these transitions include temperature, pressure, and the intermolecular forces between particles. When these factors change, the arrangement and movement of particles in the substance can also change, leading to a phase change.
A change in energy, such as heating or cooling, always accompanies a phase change in matter. This energy is required to break or form intermolecular forces between particles in order to change the physical state of the material.
Changing the temperature or pressure of a material we can change the phase.

A horizontal line indicating a phase change from solid to liquid or liquid to gas does not represent a step on the heating curve of water. Instead, it represents the energy required for the phase change to occur without a change in temperature.
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Heat associated with phase change is called Latent Heat
A change of phase occur, from liquid to gas.
its a phase change
Congruent phase transformations occur when a substance changes from one phase to another without any change in composition, while incongruent phase transformations involve a change in composition during the phase transition.
Motion occurs when there is speed. A change of speed is not required.
The heat of fusion is the energy required to change a substance from a solid to a liquid, while the heat of vaporization is the energy needed to change a substance from a liquid to a gas. Both are types of phase changes that require specific amounts of energy to occur.
The energy per unit mass required to complete a phase change is called the latent heat. It represents the energy needed to change the state of a substance without changing its temperature.
