I really need your help guysHere goes:1.Analyze the possible source of error in this experiment. What step could have been taken to minimize the effect of heat gain from and losses to the room?Explain how calorimeter minimizes heat gain and losses from A) Conduction.Use a B) Convection.C) Radiation.2.List and describe briefly three industrial processes where heat exchange is of vital importance.3.Name and describe briefly three typical heat exchangers use in industry.4.Why is water the medium used in so many heat exchange process? List as many reasons as you can think of.
The calorimeter is designed to isolate the water around the bomb from the environment by use of insulation. But even stirring inputs energy because work is transformed in to heat and the temperature of the water rises after a fairly short time. 2. Building air conditioner (like in an office building) Condensation of air to a liquid for distillation to obtain the different gases. Heating intake water and air into burners such as a coal fired power plant. 3. Condensers are used in all distillation processes to condense gases to liquid so that they can be returned to the top of the distillation tower. Boilers are used on the bottom of distillation columns to form gases to return to the bottom of the column. 4. Water is cheap, non-hazardous when it isn't steam, and it is easy to get. Most plants that use a lot of water are located so that they will be by a constant source, like a river. Also, its properties such as its heat capacity, enthalpy, etc
The calorimeter is designed to isolate the water around the bomb from the environment by use of insulation. But you have to stir the water so that it can be considered well mixed and so that the water temperature is the same through out the interior. But even stirring inputs energy because work is transformed in to heat and the temperature of the water rises after a fairly short time. So I would say that the main source of error is in measuring the work required to make the bath well stirred. This time is so short that if the temperature and air flow around the device does not change, and the air is kept as still as possible then there is little other chance of external influence. The main error is probably in your ability to measure the temperature and the time. I insulation of the device prevents radiation and greatly slows conduction and the air movement is the convection. 2.

These devices can make air flow without a fan, so they are the most practical on a large scale. 4. Water is cheap, non-hazardous when it isn't steam, and it is easy to get. Most plants that use a lot of water are located so that they will be by a constant source, like a river. Also, its properties such as its heat capacity, enthalpy, etc. are well studied and readily available. That's what chemical engineers do for 4 years is more or less study water.
