Question

An open vessel containing air at 27°Cwas cooled to a certain
temperature at which the number of moles increased by 25%.
Calculate the final temperature to which the gas is cooled.​

Answer 1

Answer:

Hi mate Here's your answer.

Explanation:

PV = nRT

since pressure and volume is constant,

nT = constant

27°C = 300K

n1T1 = n2T2.

T2 = T1/1.25

= 300/1.25

= 240K

So the final temperature is 273 - 240 = 233°C
