Step-by-step explanation:
Solubility is the ability to dissolve within a solvent to form a mixture called a solution
If a substance is soluble, it dissolves in water
If a substance is insoluble in water - it does not dissolve
Boling point - the temperature at which a substance in its liquid state
converts into the same substance in its gas state.
Water boils at 100 degree centigrade.
Melting point - the temperature at which a substance in its solid state
converts into the same substance in a liquid state.
Ice melts at 0 degree centigrade.
Water freezes at 0 degree centigrade.
How much matter (mass) is packed into a specific space (volume).
