First Law of Thermodynamics: Energy is neither created nor destroyed, but can be converted from one form to another form.
Second Law of Thermodynamics: Energy, which exists at various levels, is available for use only if it can move from a higher to a lower level.
Ideal or Perfect Gas Laws
Gases may consist of one specific gas or may be constituent of number of gases. An ideal or perfect gas is one, which obeys below mentioned Boyle’s Law and Charle’s Law. Perfect gases do not exist in practice.
Boyle’s Law – states that at a constant temperature, the volume of an ideal gas decreases with increase in pressure.

Boyle’s Law – states that at a constant temperature, the volume of an ideal gas decreases with increase in pressure.
P1V1 = P2V2 = CONSTANT
Charle’s Law – states that at constant pressure, the volume of an ideal gas will increase as the temperature increases.
V1/T1=V2/T2=CONSTANT
Amonton’s Law – states that at constant volume, the pressure of an ideal gas will increase as the temperature increases.
P1/T1=P2/T2=CONSTANT
Avagadro’s Law – states that equal volume of gas under same condition of temperature and pressure contains same number of molecules.
