Explanation:
Equation for Calcium Hydroxide Dissolving in Water | Ca(OH)2 + H2O
When calcium carbonate is heated, it breaks down to form calcium oxide and carbon dioxide.
Thermal decomposition is the process in which heat is required.
It is also known as thermolysis.
It is processed in which a compound breaks into two or more products when the heat is supplied.
This reaction is used for the production of oxygen.
This reaction is also used for production of acidic as well as basic oxides.
CaCO3 on thermal decomposition gives:
CaCO3→CaO+CO2
CaO→ Basic oxide.
CO2→ Acidic oxide.
Answer is: density of the substance, energy of the substance, intermolecular bonds between particles.
Melting is a physical change (process), the same substance is present before and after the change, so chemical bonds and melting point of the substance are not changed.
Density of liquids are usually less than in solids, because atoms are further apart.
Liquids have higher energy and atoms or molecules move faster.
Intermolecular bonds are weaker in liquids.
