3. Based on your answers, why is it warmer in summer than in winter? It is warmer in the summer then in the winter because the Earth’s tilt is

Energy can be transformed but cannot be got rid of. There are lots of forms of energy but chemical energy is the most common form of energy. Energy is a chemical bond that combines atoms or molecules with each other. When the new bond is formed between to atoms the energy helps the formation. The energy that helps is normally heat energy but can also be light or electrical. When the bond is broken atoms get realised as does the energy in the bond.

Suppose you have a flashlight in your hand. Describe the transformations of energy that take place to allow that flashlight to give off light. Be sure to include where waste energy is given off.

It implies that it is possible to make coal a fuel source that is free of (or very low in) carbon dioxide emissions and other pollutant emissions. Some of the techniques that would be used to accomplish this include chemically washing minerals and impurities from the coal, gasification (see also IGCC), treating the flue gases with steam to remove sulfur dioxide, carbon capture and storage technologies to capture the carbon dioxide from the flue gas and dewatering lower rank coals (brown coals) to improve the calorific value, and thus the efficiency of the conversion into electricity.

Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the buried remains of plants and animals that lived millions of years ago.

Another example of converted energy we can find in our movement. For this to happen we need the chemical energy first, which makes the electrical energy. This is converted to electrical energy for the nerve production, which goes back to chemical energy for the muscle contraction. At the end, the thermal energy which has the waste energy is converted to kinetic energy which produces the movement.

In 1930s the thermal power by coal, was becoming an unprecedented era of great development. In the mid of 1950s the capacity of thermal power generating units improved from 200 to 300 megawatt to 600 megawatt. In 1973, the largest thermal power was 1300 MW. At the end of the 1980s, the world's largest thermal power plant with a capacity of 4400 MW was Japan's Kagoshima thermal power plant. However, people found that the bigger the unit, the lower the reliability and the availability. Thus in the early 1990s, the thermal power became stable at the unit capacity of 300 to 700 MW. (Barrow, 126)

7) Explain why temperatures on average become cooler and seasonality becomes greater as one moves from the equator toward the poles (use a diagram of the orbit of the earth

Because of technical improvements, nonrenewables are found, extracted, and employed more efficiently than ever. Since 2000, companies have located more natural gas sources in the United States. This occurred because of advances in exploration methods. New ways to process coal have led to fewer impurities. The energy efficiency of coal has also improved so that more energy can be created from less coal.

To begin, many Canadian households in today’s society lack the focus to conserve energy with

According to statistical data “Almost all (95%) of the world's transportation energy comes from petroleum-based fuels, largely gasoline and diesel.” (United States Environmental Protection Agency, n.d.).

* Use as many fans as possible in the summer to help keep your ac bill down

There are pipes with flowing water around the boiler, the heat energy from the burning coals boils this water and creates steam, and since the steam is trapped in a tube it is under high pressure and moves very quickly. . During the process of transforming/transferring energy there will always be energy lost to the environment as heat.

Coal, a mineral I have discussed previously, is necessary to our everyday lives. Coal is an incredible source of energy; it heats our houses and buildings, and also fuels stoves. You may often wonder where this extremely useful mineral comes from. Coal does not just appear; it needs to be mined through a process which results in our being able to utilize it. Coal mining is fairly inexpensive, is carried out on a large scale and can be mined in either underground or surface mines.

Other types of energy lie between kinetic and potential energy or are an amalgamation of both types.
