Three things are usually required for a chemical explosion: a chemical reaction that occurs very rapidly, a large increase in gas pressure, and a confined-reaction vessel in which the pressure of the gaseous products can increase to a point that the gases break violently out of the container. In this chemistry and physics science fair … Read more
There are sources of energy that are renewable and do not cause so many pollutants, however they only contribute a smaller amount to the energy pyramid. These sources include hydro-electric power, wind power, solar energy and biomass energy. Most of these fuel sources do not produce as much energy as efficiently as the majority of … Read more
As the population Increased, the demand for more products, such as clothing, shoes, and household items required more energy to be produced. The increased use of machines eventually led to an increased need for power. The needed power could only come from natural resources. Causes . Some of the materials needed are renewable resources, such … Read more
