 First Law of Thermodynamics What is it? The First Law of Thermodynamics states that the amount of heat energy contained within a closed system is always constant. This is the basis of the principle of conservation of energy. Give me an example! When a battery powered light is switched on and heat is produced, that heat energy actually already existed inside the system as chemical energy inside the battery. So no energy is either gained or lost as a result of switching on the light. Copyright ©2010, PCS Edventures, Inc. All Rights Reserved. |
