Question

A gas of volume 2litres at 1000°c is cooled to 0°c at constant pressure.find the new volume of the gas
​

Answer 1

Answer:

༺☞from ideal gas equation, PV = nRT

So, this gives V= PnRT

so, V is proportional to absolute temperature and inversely proportional to the pressure of the gas

Now temperature is made half and pressure is made 2 times

So, clearly the volume becomes one-fourth of it's original value.

So, 500 ml is the correct answer...............꧂

Answer 2

Answer:

according to Charles law,

V1 / T1 = V2/T2

V1 = 2L

T1 =1000⁰c = 1000 + 273 = 1273K

T2 = 0⁰c = 0 + 273 = 273K

then

new volume

V2 = V1 T2 / T1

= 2 × 273 / 1273

= 0.43L.

hope it is helpful✌.
