The Three Laws Of Thermodynamics

Thermodynamics is used in our everyday lives, from melting ice cubes gravitating the heat from the ice to its equilibrium, and from sweating in crowded room transferring the heat from your body to sweat because of all the warm bodies crowding the room, and also to simple things like flipping a light switch, which relies on electricity to turn it on. The laws of thermodynamics are needed in our lives and are used so much that if we did not have the three distinct laws of thermodynamics society would not be able to function as well as it does now. This paper is about the three different laws of thermodynamics, law one conservation of energy (heat engine), law two involving isolated systems and law three including temperatures approaching zero …show more content…
This means that heat energy cannot be created or destroyed. This means that any energy in the universe is constant and will not stop. For example, a pendulum moves once put in motion but will gradually slow down over time and eventually come to a rest, but if it could keep a steady motion the pendulum would use energy and transfer heat because of friction. Due to the first law of thermodynamics, energy will diminish to make up for the energy lost as heat until the pendulum comes to a rest. The first law of thermodynamics can be used to conserve energy by just using heat, but also is not as useful compared to other options like electric instead of just …show more content…
In the limiting case, for reversible processes this sum remains unchanged. The second law of thermodynamics is pretty much saying that it requires work to make something disordered or ordered. For example, work is usually needed to make order out of disorder, so energy must be in use to make an effectively ordered state. So say there is a group of bricks sitting on the ground scattered across the floor. To order the scattered bricks you would need to apply yourself and put in work so that the bricks will not be scattered, but instead ordered. Another example is when order can be produced with an expenditure of energy. The ordered associated with life on earth is made with help from the sun energy. For example, plants use energy from the sun in little energy factories called chloroplast. Using chlorophyll in the method called photosynthesis, they transfer the energy from the sun into somewhere that can be in a stored form in ordered sugar molecules. Water and carbon in a disordered from are joined together to form the more ordered sugar molecules. The second law of thermodynamics is useful with putting away and (re)building things, but other than that it is not used in society as much as the other three
