heat exchanger is a device built for efficient heat transfer from one medium to another. The media may be separated by a solid wall‚ so that they never mix‚ or they may be in direct contact.[1] They are widely used in space heating‚ refrigeration‚ air conditioning‚ power plants‚ chemical plants‚ petrochemical plants‚ petroleum refineries‚ natural gas processing‚ and sewage treatment. One common example of a heat exchanger is the radiator in a car‚ in which the heat source‚ being a hot engine-cooling

Heat of Combustion Questions 1. When bonds are broken‚ energy is required. When bond are formed‚ energy is released. All combustion reactions are exothermic. Suggest a reason for this in terms of the bonds broken and bonds formed. The energy required to break the bonds is greater than the energy required to form. 2. Explain why the heat of combustion of alkanols increases as the length of the carbon chain increases. The heat of combustion of alkanol increases as the length of carbon chain

Heat energy Temperature – measure of the average KE of the particles in a substance‚ measured in degrees Celsius or degrees Kelvin. Celsius 0⁰C (freezing point of water) to 100⁰C (boiling point of water) Kelvin 0 K (absolute zero‚ particles stop moving theoretically)‚ equivalent to -273.15⁰C. Uses the same scale for increase‚ ie. a 1⁰C increase in temperature equates to a 1K increase in temperature. Heat – amount of energy transferred‚ measured in Joules (J) Kinetic Energy‚ Thermal

Business Law 110 Capacity and Legality Question and Problems 1. In the United States the idea of an “age of majority” for granted; the only question is whether it should be 18‚ 19‚ or 21. Though in Great Britain there is no age at which a young person acquires the legal capacity to enter into a contract. British courts will not enforce contracts with immature minors. However‚ they make the decision of whether a person is too immature to enter into contract on a case-by-case basis. If the

Heat Pump ------------------------------------------------- A heat pump can provide an alternative to using your air conditioner. * Heat pumps can supply heat‚ cooling‚ and hot water. * Your climate and site will determine the type of heat pump most appropriate for your home. For climates with moderate heating and cooling needs‚ heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator‚ heat pumps use electricity to move heat from a
