10 Interesting Fact About Thermodynamics

Transcript:

Languages:

• Thermodynamics is a branch of physics that studies energy changes in the physics system.
• The term thermodynamics comes from the Greek thermo which means heat and dynamis which means motion.
• The first law of thermodynamics states that energy cannot be created or destroyed, can only change shape.
• The second law of thermodynamics states that entropy always increases in a closed system.
• The term heat machine refers to the engine that utilizes heat to produce mechanical energy.
• The concept of absolute temperature was introduced by Lord Kelvin and called the Kelvin scale.
• The term enthalpy is used to describe the amount of energy contained in the system.
• The term entropy illustrates the level of molecular irregularities in the system.
• Endothermic reactions require energy to occur, while exothermic reactions release energy.
• The term Gibbs free energy is used to measure the ability of a system to do work.
