Dissolution Process
Dissolving Dissolving means that the solute diffuses into the solvent and mixes. It is a common case that salt or sugar is dissolved in water. Solvents are often liquid, mostly water. The Earth’s atmosphere is a … more
Status Change of Water
Melting point and heat of fusion When heat is applied to ice (solid), the temperature rises gradually. By the way, while the ice is melting, the temperature does not rise. Temperature is kept constant, and the … more
