Question

At the temperature in degree centigrade will the volume of a gas ,which is originally at 0 degree centigrade ,double itself,pressure remaining constant.

Answer 1

At 273 degrees centigrade the pressure remaining will be constant.

Explanation:

First consider the initial volumes as

$V_{1} =x$, $T_{1} =273K$, $V_{2} =2x$, $T_{2} =?$

And then Use ideal gas equation:

     PV = nRT

Here,

n=fixed number of moles .  

At constant temperature and R is a constant.

so volume V increases with temperature T.

And then $T^{0} C=T(Kelvin)-273$

If volume doubles then temperature also doubles, T= 546.30K

At the absolute temperature T= 0°C = 273.15 Kelvin.
