Tipler and Gene talk about heating and working whereby they expound further on thermodynamics. The first outline the main difference between heating and working followed by the laws associated with thermodynamics. In these categories, apart from discussing, the authors also use symbols and equations, which are usually easy to comprehend. The authors’ model of narration is quite recommendable; this is because of the easy grammar understandable to the readers. Apart from easy grammar, the author also uses many examples and small notes that act as extensions of information. According to Tipler and Gene, heating is the process of energy conveyance in relation to heat.
For instance, when a cold spoon is put in hot tea, there is usually energy transmittance from one body to the second. That is, while hot tea heats the spoon, similarly, the spoon cools the tea. Conversely, working also involves energy conveyance but unlike heating, there is no heat involved. For instance, when a person pushes a heavy load, the load and the ground have similar temperatures but the load normally become hotter when pushed on the ground.
In this case, the internal energy of the load increases due to continuous friction with the ground augments. According to Tipler and Gene, whereas the symbol of energy received by work is ∆W, similarly, the symbol obtained from heating is ∆Q. systematically; this leads to the next topic, which is on thermodynamics laws. The authors state that the 1st thermodynamics law is usually on energy conservation. The author further states if energy is put in a system, this normally results in energy increasing. Apart from the first law, it is also the 0th law of dynamics whereby Tipler and Gene state that this is because there are some situations where no energy transfer takes place.
By giving the example of a fish in a bowl, the author states that since the fish is cold-blooded, there is usually no exchange of energy since they are at the same temperature with water.
