Question

Prove that the volume of a gas at 273°C is twice
its volume at 273 K, at constant pressure.
​

Answer 1

Answer:

at constant pressure volume is directly proportional to temperature .

e.g

V=kT

where k is proportionality constant.

here you take temperature only in Kelvin .

now,

when T =273 Celsius

T= 273 +273 =2. (273) Kelvin

V=2(273) k

when T = 273 Kelvin

V" =(273) k

now,

V=2V"

hence proved
