Question

A sample of krypton gas at a pressure of 752 mm Hg and a temperature of 28 °C, occupies a volume of 11.6 liters. If the gas is cooled at constant pressure to a temperature of -21 °C, the volume of the gas sample will be L.

Answer 1

Question A sample of krypton gas at a preessure of 752 mm Hg and a temperature of 28°c, occupies a volume of 11.6 liters. If the gas is cooled at constant pressure to a temperature of -21°c, the volume of th gas Sample will be L. T. Ami According to ideal gay equation' NOTE Pr=nRT the he the P Dabressure, vis the volume and t is the temperature of the gan non the number of molls. when, p and n is constand, NXT V = constant ret, us consider that krypton behares ideally, N = 11.6L & Ti = 28°c = 3016 T2 = -21°c = 252k N2 = ?

c. N2 11. = 252 V2 = g.IL 301 252 or is preoportional to T , so when T decreases, & also decreases. c. The volume of the gas sample will be g.712 when the temperature in -21°c NOTEL Krypton is a real gay a so it can't totally behave ideally but copo here the calcation is done by assuming the ideal gas behaviour of krypton,
