    Which of the following best defines pressure? (Chemistry)

    Which of the following best defines pressure?
    A) It is the total amount of heat per unit area held by a substance.
    B) It is the force applied to a unit area of surface.
    C) It is the average kinetic energy of molecules.
    D) It is equal to volume divided by the product of moles and temperature.

    *The Answer is B but can someone explain why each one is wrong and why B is right. Only D seems to make sense to me.
