Question

How do we use thermodynamics in everyday life?

Answer 1

Thermodynamics:

1. It is that part of science that is concerned with the conditions that material systems may assume and the changes in conditions that may occur either spontaneously or as a result of interactions between systems.
2. The word “thermodynamics” was derived from the Greek words there (heat) and dynamics means (force).

Following are the ways we use thermodynamics in everyday life:

1. Taking a bath: Take a moment to imagine someone taking a really long bath. The water in the bathtub is quite hot, reaching temperatures of up to 120 degrees Fahrenheit during and immediately after filling it. The water will then be turned off, and the person will dive under it. Since the water is warmer than the person's body temperature, it initially seems comfortable to be in the water. Eventually, though, some of the heat from the water will have been transmitted to the person, bringing the two temperatures together. Since this is not a closed system, the bath water will eventually chill as heat is lost to the atmosphere over a period of time.
2. Sweating in a crowded room: The rules of thermodynamics are observed by the human body. Think about what it would be like to be surrounded by many other individuals in a small, cramped space. Your body uses this process to cool itself off. Sweat gains heat from your body through conduction. Sweat loses heat when it evaporates from your body, becoming more disorganized and raising the temperature of the surrounding air as a result as it absorbs more heat from your body.
