Question

derive combined gas equation​

Answer 1

Answer:

from Boyle's law we have

$v \alpha \frac{1}{p}$

when T is constant ⬆️⬆️

From Charl's law we have

$v \alpha t$

when P is constant ⬆️⬆️

combining these two laws we get

$v \alpha \frac{t}{p}$

when P & T are variable ⬆️⬆️

$v = \frac{kt}{p} \\ \frac{pv}{t} = k$

where K is constant ⬆️⬆️

● This is combined gas equation.

Answer 2

Derivation of the Combined Gas Law

The combined gas law is an amalgamation of the three previously known laws which are- Boyle's law PV = K, Charles law V/T = K, and Gay-Lussac's law P/T = K. Therefore, the formula of combined gas law is PV/T = K, Where P = pressure, T = temperature, V = volume, K is constant.
