Freezing, burning, and evaporation are all examples of phase changes or state changes in matter. Freezing is the transition from liquid to solid, burning typically involves a chemical reaction (combustion) that transforms substances, and evaporation is the process of a liquid turning into a gas. Each of these processes involves energy transfer and changes in the physical or chemical properties of the substances involved.
distillation
1: filtration: is the easiest way to do it but only works up to a certain point. 2: evaporation: just heat your compound until the liquid starts evaproating (if you want to use it, you have to condensate it again) and when all liquid is "gone", the solid should be left.
A chemical change is a change in which a substance turns into a completely different substance that can't be reversed. A chemical change often happens when a substance burns (not to be confused with evaporation or melting of a substance), changes colors, a substance spoils or rusts, photosynthesis or respiration, and/or a substance tarnishes.Some examples are a bike rusting, burning bread to make toast, fireworks exploding, milk spoiling, a leaf changing color, mixing eggs and flour for a batter, baking a cake, etc.A chemical change will NOT dissolve, go through a state of matter (sublimation, decomposition, melting, freezing, evaporation, and condensation), breaking or tearing of a substance, and/or anything that can be reversed back.A chemical change is one in which one or more new substances are formed. Simple examples include burning and rusting.
Evaporation is the process in which there is a change of state from liquid to gas. Condensation it is the process in which there is a change of state from gaseous to liquid or solid. Evaporation takes place from surfaces, all the time at all places Condensation can take place on surfaces, or at any place in a gas, though it is often aided by the presence of dust or other small particles. Evaporation absorbs energy. Condensation gives out energy.
Water, like all substances, has only one freezing/melting point, which is 0 C or 32 degrees F.

Burning of natural gas, evaporation of water, and formation of bonds in chemical reactions are all examples of processes that involve enthalpy changes.
The ones I know are melting, freezing, condensation, evaporation (or vaporization), and sublimating. These are definitely NOT ALL of them though.Ur welcome,:0)
All of the following are examples of chemical change except physical changes such as melting, freezing, or dissolving. In a chemical change, the substances involved undergo a transformation that results in new chemical properties, while in a physical change, the substance remains the same at the molecular level. Examples of chemical changes include rusting, burning, and digestion.
Evaporation is the process of turning liquid into a gas. Examples of these are the evaporation of water when it is boiled and the evaporation of alcohol at room temperature.

Burning chemically alters a substance, creating different / new substances as a result. Melting, freezing, and evaporating are all different phases of the same substance.
