Stirling Engine Model

Q1- How does a Stirling engine work? Ans1- Every Stirling engine has a sealed cylinder with one part hot and the other cold. The working gas inside the engine (which is often air, helium, or hydrogen) is moved by a mechanism from the hot side to the cold side. When the gas is on the hot side it expands and pushes up on a piston. Q2- What is the use of Stirling engine? Ans2- 1) Stirling engine is used in some submarines because this engine produce very less noise thus serving its purpose for submarine which is used for secret purposes. 2) It is used as solar stirling engine in some countries like New Zealand to generate electricity.
