Question

Define Boyle 's law and Charles law in physics
only give me right answer ​

Answer 1

$\huge{\textbf{\underline{Boyles\;law}}}$

It states that "the volume of a given mass of gas is inversely proportional to its pressure, at constant temperature".

i,e., when the temperature (T) is held constant, V ∝ 1/p ⟹ PV = Constant

$\huge{\textbf{\underline{Charles\;law}}}$

It states that "the volume of the given mass of a gas is directly proportional to its Absolute temperature at constant pressure".

i, e., when the pressure (P) is held constant, V ∝ T ⟹ V/T = Constant

Additional Information:-

Example for Boyle's law:-

$\bigstar$A balloon with a volume of 2.0 L is filled with a gas at 3 atmospheres. If the pressure is reduced to 0.5 atmospheres without a change in temperature, what would be the volume of the balloon?

$\implies$ Since the temperature doesn't change, Boyle's law can be used. Boyle's gas law can be expressed as:-

$\large{\boxed{\tt{PiVi = PfVf}}}$

Given:-

Pi = initial pressure

Vi = initial volume

Pf = final pressure

Vf = final volume

To find:- The final volume Vf

Vf = PiVi/Pf

Vi = 2.0 L

Pi = 3 atm

Pf = 0.5 atm

Vf = (2.0 L) (3 atm) / (0.5 atm)

Vf = 6 L / 0.5 atm

$\large{\boxed{\tt{Vf = 12 L}}}$

Example for Charle's law:-

Watch what happens to a helium balloon on a cold day. Step outside with a helium balloon on a chilly day and chances are, the balloon will crumble.

Answer 2

$\bf{\huge{\boxed{\underline{\tt{\green{Answer:}}}}}}$

Boyle's law:-

According to this law when the temperature is constant and at one mole of gas

Volume of gas is inversely proportional to the pressure of gas.

General formula:-

P1V1=P2V2

Charle's law:-

According to this law when pressure is constant and 1 mole of gas is present then volume gas is directly proportional to the temperature.

General formula :-

V1/T1=V2/T2.
