🔰🔰Important Laws and Theories:-🔰🔰
🔷🔷1. Boyles’s Law: it states that at constant
temperature, volume of a given mass of gas is
inversely proportionaltothe pressure ofthe gas.
🔶🔶2. Charles’s Law: it states that at constant
temperature, volume of a given mass of gas is
directly proportional to the temperature
measured in Kelvin.
🔷🔷3. Avogadro’s Law: it states that equal volumesof
all gases under similar pressure and
temperature conditions, contain equal number
of molecules.
🔶🔶4. Archimede’s Principle: it states that the body immersed in a fluid is buoyed up by a force equal to the
weight of the displaced fluid.
🔷🔷5. Bernoulli’s Principle: it states that for an inviscid flow of a no conducting fluid, an increase in the speed
of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential
energy.
