Thermodynamics is the study of heat and how it relates to energy or work. This discipline of physics is applicable to chemistry, and various forms of engineering, since it studies the way substances as a whole behave rather than focussing only on the behaviour of the molecules they consists of.
There are many practical applications for an understanding of thermodynamics, for example, the principles of thermodynamics help us to design more efficient engines and refrigeration systems, help us to understand why everyday materials have certain properties, and can help us to predict the reactivity of chemicals. Whether you are studying black holes or looking for the right material for an electricians’ screwdriver handle, thermodynamics and its principles come into play.
