  1. What is thermodynamic?
    The study of transformation of energy
  2. What is energy?
    The capacity to do work

    Is what done to achieve motion against an opposing force.
  4. As temperature of a gas increasing, what happens to the energy? and if the temperature decreases?
    • -Temp of the gas inc-> More energy
    • -Temp of the gas dec-> less energy
