How does entropy apply to our daily lives?

Entropy affects our daily lives in a number of ways. Simple tasks and questions such as taking a shower and wondering how water becomes hot or cold all involve the principles of entropy. Entropy doesn't always involve temperature it also involves moving, transformation of something, and dealing with electrons. So what is entropy? Entropy is a measure of the number of specific ways in which a thermodynamic system may be arranged commonly understood as a measure of disorder. An example of entropy is "When you are born your body grows larger you become stronger over time but after sometime the body will become weaker your bones will become weak and you become less functional and active in living a normal daily human life til your exhausted and this is where death takes its place". Another example of entropy is "When water needs to be heated it has to be exposed to heat energy, then when the heat enegry is exposed it transfers its particles into the water, the particles begin to move and increases its speed in a disorderly manner. So the particles move to increase the waters temperature. When the opposite of its behavior is in effect it is observed and is no longer to heat energy. When the particles decrease the water begins to cool down." So what makes things heat up? Sometimes the amount of kinetic energy is added to an object which makes the object it heats up. Basically entropy is all around us and in our daily lives. Its in our homes, cars, portable devices, and in our education. Heat can transfer in three ways and that's through radiation, conduction, and convection. Heat posses a relationship between energy and heat because heat is the mechanism of energy from an area of higher temperature to an area of lower temperature.

What is the “Second Law of Thermodynamics"? The second law of thermodynamics the branch of physical science that deals with the relations between heat and other forms of energy.
Laws of Thermodynamics "Laws we must live by"
Laws of Thermodynamics "Laws we must live by"
- Energy Cannot be Created or Destroyed
- But can be turned into a different form.
- Ordered Energy - Work Done
- Disordered Energy - Heat
- Heat work requires taking heat from a hot source and depositing waste heat to a cold supply.
- Work considered as “ordered"
- Heat energy is considered disordered
- Fridges heat our homes (Your refrigerator is the biggest energy consumer among all appliances)
- Heat is useful in winter
- Work (electricity) is used to move heat from inside the fridge to outside the fridge
- Ordered energy is ultimately converted to disordered energy
