up to 20%. The purpose of them is to hold the heat below within the property‚ reducing heat loss to the roof void and outside but also reducing the amount of heating needed to maintain the property at an ideal temperature. With insulation‚ the property will be warmer‚ more comfortable and it will cost less to heat. How loft insulation reduces heat loss? Heat will always flow from a warm area to a cold one. The colder it is outside‚ the faster heat from your home will escape into surrounding air

Combustion of Alcohols THE COMBUSTION OF ALCOHOLS PROBLEM Investigate the heat energy in a range of alcohol’s used as fuels. HYPOTHESIS I predict that octanol will release the most heat energy. This is because there is more bond energy in that molecule than the other alcohols. Within a molecule there are bond energies that are holding the atoms together. When the fuel combusts a chemical reaction takes place‚ this breaks the bonds‚ this requires energy‚ and makes new bonds this gives out energy

Geothermal Power [pic][pic][pic][pic][pic]The ground beneath our feet contains a significant amount of energy in the form of heat. All of this geothermal energy has the potential to generate geothermal power to provide large amounts of electricity. People have used geothermal energy in the form of hot springs for centuries‚ however‚ the first attempt to generate electricity from this energy source did not occur until the 20th century. The production of electricity from geothermal energy sources

Direct Geothermal Energy. This is where we use the near surface hot springs to be pumped directly into our houses and office buildings. It is pumped through a heat exchanger‚ which transfers the heat in the water to the heating systems of the buildings. Once the waters heat has peen used it is piped back into

Molar Heat of Combustion Aim: To find the molar heat of combustion for four different alkanols: 1. Methanol 2. Ethanol 3. 1-Propanol 4. 1-Butanol - And to compare the experimental value with the theoretical. Background: The Molar Heat of Combustion of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at standard atmospheric pressure‚ with the final products being carbon dioxide gas and liquid water.

already invented the heat pump. But the idea of drawing heat from the ground was not patented until 1912‚ by a man named Heinrich Zoelly. Still the geothermal heat pump was not successfully implemented until the late 1940’s. Geothermal heating and cooling takes advantage of warmth stored in the earth ground. The earth ground temperature in around 55 degrees F. (13 degrees C.) at the depth of around ten feet. A geothermal heat pump uses many different systems of transferring heat into the ground. For

Experiment to measure the latent heat of vaporisation of water Theory Latent heat of vaporisation is when a liquid is heated enough to start boiling‚ at this point‚ even if the source of heat keeps heating the liquid‚ the liquid’s temperature will not rise any further until all of the liquid is converted to gas. For example‚ if water is boiling in a kettle‚ and the kettle is left on whist the water is boiling‚ the water’s temperature will not exceed 100°C because all the heat energy from the kettle is

alternative heat sources in order to save on the high-energy costs of heating a home. Many alternatives have been used. However‚ over the past twenty years‚ some homeowners have turned to just one of those alternative heating sources‚ and that heating source is geothermal heat. Geothermal heating is the new efficient‚ long-term cost effective‚ and environmentally safe‚ way to heat a home. Geothermal technology uses the heat from the sun-soaked soil underground (about 4 to 6 ft) to heat a structure

JOE WILLIS: FEELING THE HEAT IN THAILAND JOE WILLIS: FEELING THE HEAT IN THAILAND Joe Willis and his team are faced with a massive mess that they must clean up and restore order back to the entity. Throughout the story Joe is read as the protagonist‚ but to the workers he aims to empower and improve to increase performance/productivity he is seen as the antagonist and only there because he is on a ‘witch hunt’. The fear instilled because of word of mouth that he is from ‘internal audit’ makes

extremely hot molten rock called magma. These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly. A geothermal heat pump system can take advantage of the constant temperature of the upper ten feet (three meters) of the Earth’s surface to heat a home in the winter‚ while extracting heat from the building and transferring it back to the relatively cooler ground in the summer. Geothermal water from deeper in the Earth can
