1 .Chemical reactions may release or consume energy. Some reactions, such as burning fossil fuels, release large amounts of energy by losing heat and emitting light.
2. Light can initiate many chemical reactions such as the evolution of urban smog.
3. The total energy of the universe is constant. Energy can be transferred by collisions in chemical reactions. However, it can never be destroyed.
4. Everything becomes less orderly over time. In energy transfer the overall effect of the energy spreads out uniformly like the warming of our surroundings as we burn fossil fuels.
