If a certain substance has reached a temperature at which it either melts, freezes, evaporates, ect.
It is caused by the position of the moon that eventually changes because of its revolution and rotation.
Phase changes of water, such as melting, freezing, boiling, and condensation, are caused by changes in temperature and pressure. When water reaches its melting or boiling point, the intermolecular forces break or form, resulting in a change in the water's molecular arrangement and a transition to a different phase.
Phase changes are accompanied with optical contrast and therefore the feasibility of phase.
Phase modulation and frequency modulation are related because changes in the phase of a signal result in corresponding changes in its frequency. When the phase of a signal is modulated, it causes variations in the frequency of the signal as well. Therefore, in practice, it is difficult to separate phase modulation from frequency modulation, especially in communication systems where both aspects are interconnected.
its physical changes
Puberty
The phase of water changes in response to temperature and pressure. When water is heated, it changes from a solid (ice) to a liquid (water) at its melting point, and then to a gas (steam) at its boiling point. Conversely, when water cools down, it transitions from a gas to a liquid to a solid.
Because it changes its form.
Because atoms only go through phase changes
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
Phase changes are physical changes in nature. They involve a change in the state of matter (solid, liquid, gas) rather than a change in the chemical composition of the substance. Heating or cooling a substance can trigger phase changes.
