Gas is dependant on temperature,pressue and volume so we have made this app to learn the basic understanding physics law.Now we have defined all the relationships in visualise and more animated form Gas principals.This app helps to educate kids and helps them to learn in depth concepts.The laws describing the behaviour of gases under fixed pressure, volume and absolute temperature conditions are called Gas Laws. The basic gas laws were discovered by the end of the 18th century when scientists found out that relationships between pressure, volume and temperature of a sample of gas could be obtained which would hold to approximation for all gases.
