Apr 24, 2019 · Hence thermodynamics becomes a guide to design devices that best perform as we would. The primary impact thermodynamics has on our daily lives is the many ways it shows us how to use energy efficiently, and minimize the wastes that inevitably accompany that use. One of the earliest examples appeared at the birth of the subject, when the work by ...
- Automobile Engine. When you drive a car, the process begins at the fuel pump, where you fill the gas tank with gasoline. Gasoline is a chemical fuel that contains a substantial amount of potential energy stored in the form of chemical bonds between its atoms.
- Human Metabolism. Human metabolism is a complex and intricate process governed by the first law of thermodynamics. When you consume food, your body extracts the chemical energy stored in the macronutrients, such as carbohydrates, fats, and proteins.
- Refrigeration. Refrigeration is a practical application of the first law of thermodynamics, showcasing how energy can be effectively transferred from one location to another to achieve a specific goal.
- Electric Power Plant. Electric power plants play a crucial role in supplying the energy required to power our homes, industries, and modern society at large.
The first law of thermodynamics states that "the glass is half empty," whereas the conservation of energy law shows that "the glass is half full." The thermodynamics law emphasizes the bad news: that one can never get more energy out of a machine than the energy put into it.
May 10, 2021 · Chemical thermodynamics describes the change in enthalpy (∆H) and entropy (∆S) during a chemical reaction or change of state. The process will only be possible if the enthalpy and entropy changes combine to give a negative value for the change in free energy (∆G), where ∆G = ∆H – T∆S. The formation of bonds is exothermic, which ...

Every heat engine uses four basic processes that interact with the surroundings to accomplish the engine’s job. These processes are heat input, heat rejection, work input, and work output. Take your automobile engine as an example of a heat engine. Here are the four basic processes that go on under the hood:

Jul 21, 2021 · 3. Melting of ice cubes. The melting of the ice cube is a classic example of the first law of thermodynamics occurring in our daily lives. When you leave an ice cube out in the open, you will notice it melting and converting to water in just a few minutes. This phenomenon happens because the ice absorbs the heat from the surrounding air ...
