Thermodynamics

Le résumé fourni par la source

This chapter explains the system in which the reaction of interest being studied and the surroundings are the rest of the space around the system. It points out that the system that is supplemented by surroundings is called the universe. It also outlines different types of systems that vary according to their transfer of matter and energy and elaborates on how energy can take the form of either heat or work. The transfer of energy as heat arises when there is a difference in temperature. Work is carried out by a reaction when it opposes a force. An example is when gas is produced, and it expands against external pressure. The chapter clarifies how work is done on the system if the atmosphere pushes in on the reaction and compresses any gaseous components.
