'Water'. A compound is 'impure', that means it contains more than one
type of atom. When a group of atoms combine, they create a molecule.

Answer:Comparison of Ionic and Covalent Bonds
In an ionic bond, the atoms are bound together by the electrostatic forces in the attraction between ions of opposite charge. ... For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons.

Answer:
According to Kinetic Molecular theory, Temperature is directly proportional to the Average Kinetic energy of a molecules.
Explanation:
If the mass of the particles in a container is constant, then its moving molecules cause the gas gets warmer. On collision of molecules, Kinetic energy of molecules get high, so as a result, temperature gets high.
Fast moving of particles increases the temperature.
