thrmodynamics

Thermodynamics first year Engineering chemistry The world is becoming more and more energy conscious. With ever increasing energy costs it becoming more and more important to minimize energy use and thus save energy. A change in the form of energy (i.e. conversion from one type of energy to another) does not only take place in chemical reaction (e.g. in a forest fire) but also when a physical change takes place e.g. when a gas is compressed for example when you pump your bicycle tire. Firstly we are going to concentrate on certain aspects of thermodynamics (which is regarded as the science of energy it all its forms) and then we will focus on thermo-chemistry, which is the subsection of thermodynamics that describes reaction heat effects. The mechanical, megatronic and chemical engineering students will have follow-up modules in their 2 nd and 3rd years where most of the aspects of thermodynamics will be investigated in more detail. To be able to understand the typical questions that need to be answered, it is required to be aware of the various forms of energy associated with a specific quantity of matter, namely: (a) Internal energy (b) Displacement work (c) Kinetic energy (d) Potential energy (e) Flow work (f) Technical work (g) Heat (h) Chemical energy The creation of energy to nuclear reactions or due to the effects of external electrical or magnetic fields will not be considered in this course
