ICSE class 9 Chemistry, Study Of GAS LAWS-Boyle’s law
DAY 2 STUDY OF GAS LAW
Measurable properties of gas
| Pressure | Volume |
Boyel’s Law
| Volume | Temperature |
Charles’ law
| Pressure | Temperature |
Gay lussac’s law
| Volume | No of Moles (n) |
Avogadro law
As per our Board syllabus we discuss only Boyel’s Law & Charles’ law
Boyels Law: At constant temperature the volume of a given mass of gas is inversely proportional to its pressure.
Mathematically, Boyle’s law may be expressed as
V α 1/P ( At constant temperature and mass)
V = K/P or PV = K ( constant)
Let V1 be the volume of the gas at a pressure P1, at constant temperature, if the pressure be increased to P2 then the volume will decrease to V2, According to the law
P1V1 = P2 V2 = Constant
The product of volume and pressure of a given mass of gas is constant at a constant temperature
