What is the usefulfulness of thermodynamics? what does it help us do? does it help us in inventing new things?

Question

I just need to know what thermodynamics is for besides knowledge

Answer 1

very helpful, whether you're designing refrigerators or nuclear power plants or a city water system or ...(tons of examples, but I'm only allotted so much time per question)

Answer 2

Thermondynamics is used quite often by engineers who design processes or equipment. For example, think about people who design engines. They have to be able to calculate how much heat is expected to be generated and the cooling system to keep the parts below a certain temperature, otherwise parts warp or wear or leak or do all kinds of things that you don't want them to do. Power plants use either nuclear power or coal or oil to generate heat to create steam and turn turbines to power genrators that make the electricity that runs your appliances and lights your home, school, or businesses. The people who design these power plants use thermodynamics. People who design jets have to compensate for the fact that surfaces on the nose or wings are heated by air friction. They need to make sure that the design can handle that heat load and they use thermodynamics to do those calculations. How about all the plastic you see around you. You're monitor has a lot of plastic parts. Your keyboard has a lot of plastic. There are tons of plastic items. Many of these are made by heating up plastic pellets in a special piece of equipment called an extruder and then injecting this liquid plastic into molds. The people who develop those molds and the extruder and the people who develop the plastic pellets all use thermodynamics to understand heat flow.

Answer 3

In addition to what "Tammi D" said, it is also useful in determining what chemical reactions are possible, and under what conditions.

It is mostly used for designing motors, generators, A/C systems & refridgerators (thermodynamics is literally the study of how heat moves).

Aerospace engineers also use it, since heat flow affects airflow.
