Question

Define fusion, solidification,sublimation and vaporisation.

Answer 1

fusion is the process of conversion of solid into liquid..
solidification is the process of conversion of liquid into solid.
sublimation is the process by which solid directly changes into gaseous state without changing in liquid state and vice versa.
vaporization is the process of conversion of liquid into gaseous state..

Answer 2

Fusion is the combining two or more things tigether into one solidification, also known as freezing, is a ohase change of matter that result in the production of solid. Generally this occurs when the temperature of a liquid is lowered below a freezing point sublimation is a chemical process where a solid turn inti a gas without goinv through a liquid gas. An example of sublimation is when ice cubes shrink in the freezer vaporisation or (vapourisation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization :evaporation or boiling. Evaporation is a surface phenomenon , whereas boiling is a bulk phenomenon
