state two difference between melting of solid and dissolving of solid in water
Answers
Answer:In melting only one substance is involved and the liquid and solid are the same material. ... Dissolving involves two materials; the resulting solution is a mixture of both. The dissolved substance is still present in the solution even though it can't be seen.
Explanation:HOPE IT HELPS
When a solid dissolves the solid (solute) and the liquid (solvent) form a very close intimate mixture called a solution. ... If a solid dissolves on mixing its particles break apart and form a loose association with the liquid (solvent) particles
Therefore, dissolving salt in water is a chemical change. ... Thus, any ionic compound that is soluble in water would experience a chemical change. In contrast, dissolving a covalent compound like sugar does not result in a chemical reaction.
