Why does heating a solution usually increase solubility?
What is the added thermal energy increases molecular motion allowing solvent molecules to break apart.
What is floating booms, skimmers and sieving.
Why do substances change state?
What is adding heat increases particle energy eg:melting/evaporation.
What is the name of the mixture that is unmixable
What is immiscible liquids
Why is gas easier to compress than a solid ore in a mine?
What is a gas is much easier to compress than a solid because of the vast amount of empty space between gas particles.
