Explain how the temperature of a substance is
related to the kinetic energy of its molecules.

Temperature is directly proportional to the Kinetic Energy of molecules.

Explanation: When a certain substance is heated its molecules absorbs heat or thermal energy. Upon the absorption of heat the molecules tend to move faster since it gains energy, so its kinetic energy increases as well. An increase in temperature will result to an increase in the Kinetic energy on the molecules.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
