What is an example of the first law of thermodynamics in action

The first law of thermodynamics is a fundamental principle of physics that states that energy can neither be created nor destroyed, only transformed from one form to another. Here are some examples of the first law of thermodynamics in action:

• The melting of ice cubes: When ice cubes are left out in the open, they absorb heat from the surroundings and cool the air. The heat goes on to melt the ice, which is an example of the first law of thermodynamics.

• Eating: Human metabolism involves converting food into heat, work, and stored fat, which is another example of the first law of thermodynamics.

• Turning on the electric kettle: When we turn on the switch of an electric kettle, the electricity fires the heater, which warms the water. This is an example of the first law of thermodynamics in action.

• Combustion of coal to produce electricity: Although the maximum amount of energy available from the process is fixed by the first law of thermodynamics, the quality of energy degrades over time due to the second law of thermodynamics.

These examples illustrate how the first law of thermodynamics applies to everyday situations and how energy is transformed from one form to another.
