Timeline of thermodynamics
Thermodynamics is the study of energy and how it changes form. It has been around since the early 1800s when scientists started to study how energy works. Here is a timeline of the important developments in thermodynamics:
1800s: In the beginning of the 1800s, scientists started to study gases and how heat affects them. They came up with the idea of a "gas law" which stated that when a gas is heated, it expands (gets bigger) and increased in pressure.
1850s: Some scientists studied the total amount of energy in a system, and came up with the idea of "conservation of energy". This law said that energy could not be created or destroyed, but instead changes form. Examples of these energy changes included a hot object cooling down and a liquid turning into a gas.
1860s: Other scientists started to take the idea of conservation of energy a step further, and created the first laws of thermodynamics. These laws said that energy could be converted from one type to another, such as turning heat energy into mechanical energy.
1870s: Around this time, the idea of entropy was developed. Entropy was basically how energy was dispersed within a system; a system with more entropy was usually considered more random or chaotic.
1900s: This century saw a lot of advances in thermodynamics. Scientists studied temperatures and pressure, created models of systems, and developed new equations for understanding energy and thermodynamics. This century also saw the development of the Second Law of Thermodynamics, which said that entropy will always increase in a closed system.
Today, thermodynamics is an important field of science, used to understand complex energy systems.
