Question

volume of a flax is 500cm³. Temperature increases 25° to 35° at constant pressure. calculate the final volume of air ​

Answer 1

Explanation:

$\huge\mathfrak\blue{Answer:}$

Given:- (The increased pressure does not cause any chemical reaction). ... (Consider air to be 80% nitrogen and 20% oxygen by volume). 5 ... Calculate the pressure in the flask at 473 K.

Answer 2

$\huge\bigstar\underline\pink{Answer}$

★From Perfect gas equation PV =μRT

=> V/T=μR/P =constant.

Therefore ,V/T = constant.

★According to Charles's law for a fixed pressure,volume of a gas is ∝ to its absolute temperature.

V1/T1 = V2/T2

=> 500/25 = V2/35

=> V2 = 700cm³
