Presentation Topics•Boyle’s Law•Charles’s Law•Avogadro Law &•Applications of these law
BOYLE’S LAW
• In 1662, Robert Boyle discovered this law
Robert Boyle
Law: When Temperature remaining constant, volume of a fixed amount of gas is inversely proportional to the pressure of the gas.
Pressure and Volume are Inversely Proportional
V ∞ V = PV = K
Here,
V = Volume P = Pressure K = Proportionality Constant
CHARLES’S LAW
Jacques Charles
In 1802, Jacques Charles discovered this law
Law: When pressure remaining constant, volume of a fixed amount at gas is directly proportional to the absolute temperature of the gas.
Pressure and amountOf gas are constant
Charles’s LawVolume and Temperature are Directly Proportional
V ∞ TV = kT = k
Here, V = volume T = temperature in kelvin k = proportionality constant
AVOGADRO LAW
Amedeo Avogadro
In 1811, Amedeo Avogadro discovered this law
Law: When temperature and pressure remaining constant, volume of a fixed amount at gas is directly proportional to the number of the molecules present in the gas.
Temperature and pressureAre constant
Avogadro LawVolume and number are directly proportional
v ∞ nv = kn = k
Here, v = volume n = number k = proportionality constant
For comparing the same substance under two different sets of conditions, the law can be usefullyexpressed as follows:
=
𝑉 1
n1=𝑘
𝑉 2
n2=𝑘
Do you have any questions!!!
