First Law of Thermodynamics Examples in Real Life

First law of thermodynamics states that heat is a form of energy that can neither be created nor be destroyed, but it can only be converted from one form to another form. (i.e., The total energy of the system remains constant)

Here are some examples of first law of thermodynamics in everyday life:

#1 Conversion of light energy to chemical energy, during the photosynthesis process

#2 Conversion of electrical energy to light energy, when a light bulb is switched ON

First Law of Thermodynamics Example - Light Bulb

#3 Conversion of mechanical energy to heat energy, when we rub our hands

First Law of Thermodynamics Example - Hands

#4 Conversion of potential energy to kinetic energy, when a stone falls from the edge of a hill

First Law of Thermodynamics Example - Stone

#5 Conversion of chemical energy to heat energy, when a dry wood is burnt

First Law of Thermodynamics Example - Dry Wood

#6 Conversion of mechanical energy to heat energy, when brakes are applied to a moving bicycle

First Law of Thermodynamics Example - Bicycle

#7 Conversion of electrical energy to sound energy, when a loudspeaker is turned ON

First Law of Thermodynamics Example - Loudspeaker

#8 Conversion of potential energy to kinetic energy, when a book is pushed with the hand

First Law of Thermodynamics Example - Book

#9 Conversion of electrical energy to heat energy, when a microwave oven is turned ON

First Law of Thermodynamics Example - Microwave Oven

#10 Conversion of potential energy to kinetic energy, when a coconut falls from a tree branch

First Law of Thermodynamics Example - Coconut
