The study of the nature of heat and its conversion or relationship to other energy forms is called amount of energy in the universe is always in objects can be thought of as of energy. the first law of thermodynamics states that energy cannot or destroyed only transferred to another energy is a hidden form of energy all life and technology depends on. the second law of thermodynamics states that the of the universe can only go energy always flows from warmer objects to colder objects. the only way to keep the fires of energy burning in the universe is to add from oil, gas, or nuclear. according to the laws of physics, as we know it, the universe will end when is extinguished. word bank:
