Knowledge of the gas laws is a fundamental requirement of any training course of in thermodynamics.
The unit Change of State of Gases enables the students to study two changes of state of gases experimentally. Boyle’sLaw deals isothermic (Constant temp.) change of state on the other hand Charle’s Law deals isochoric (Constant Pressure) change of state. Air is used as a test gas and state of change is observed through two transparent vessels.
