when matter changes state either evolution or absorption of enrgy occurs for example when a solid changes to liquid or a liquid changes to gas energy is absorbed and in case of conversion of gas to liquid or liquid to solid enrgy is liberated....
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.
Physical changes in materials occur when the material undergoes a change in its physical properties without any change in its chemical composition. Examples of conditions that can cause physical changes include changes in temperature, pressure, or exposure to light or electricity. Physical changes can include changes in state (such as melting or freezing), changes in shape or size, or changes in properties (such as conductivity or solubility).
These changes usually occur in meiosis not mitosis. It causes a mixing of the alleles.

geologic changes occur suddenly
pressure and the change of state is chemical
Changes in state can occur when a substance is heated, cooled or even if an external pressure change occurs.

solid wax turns into liquid .
Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state stimulate changes to occur in the opposite direction.
Return loss refers to the reflections that occur at changes in impedance.
Sublimation occur directly from a solid to a gas, jumping over the liquid phase.

There is not a specific time when weather changes occur except for the changing of the seasons.
