    Which of the following has a direct effect on the K.E. of particles?

    A)  Pressure           

    B)         Potential energy

    C)  Temperature       

    D)         All of the above

    Correct Answer: C

    Solution :

     Particles of matter are in continuous motion. That is, they possess kinetic energy. As the temperature increases, they move faster. So, we can say that increase in temperature causes increase in kinetic energy. Hence, temperature is a direct measure of\[K.E.\]
