Energy can never be created or destroyed. Energy can only be converted between different types. Types of energy include: Thermal, kinetic, electromagnetic radiation and potential energy.   When electricity is generated from a coal powered station the energy conversion process goes as follows: Chemical energy inside coal -> Burned to make Heat -> boil water … Read more

Water is what evapourates in the drinks so water would evaporate quicker.

A pure substance is only made out of one type of element. For example hydrogen gas or nitrogen gas.   A compound has more than one element in it like sodium chloride (salt).

What makes two substances different is the molecular make up. If a substance has a molecular structure it differs from another in: 1. The amount of atoms in the molecule 2. Which atoms are in the molecule 3. The arrangement of the atoms in the molecule.   All molecules are made up of atoms. There … Read more
