Question

How does the First Law of Thermodynamics affect our lives?

Answer 1

Explanation:

1. According to the first law of thermodynamics, a system's internal energy change is equal to the sum of its net heat transfer and its network output. The first law of thermodynamics is expressed as an equation: $\Delta U\mathit{=}Q\mathit{-}W$.
2. Here, $\Delta U$ stands for the system's internal energy $U$ change. $Q$ is the total amount of heat that has been moved into and out of the system; it is also known as the net heat transferred into the system. The amount of work completed by the system, or its network, is denoted by the symbol $W$.
3. Here are a few instances where the first law of thermodynamics has been used in real life: Electric energy is converted into light energy by an electric lightbulb. Sunlight's radiant energy is transformed into chemical energy by plants. When we walk, run, or swim, the chemical energy that has been stored in our bodies is converted into kinetic energy.

The first law of thermodynamics has an impact on life in the following ways:

1. When we walk or ride a bike, we transform the chemical energy in the food into kinetic energy.
2. Radiation energy is converted into chemical energy by plants.
3. The building's cooling and heating system is based on the
