Question

explain with the help of formula the expanstion co-efficient of liquid and gas

Answer 1

The coefficient of volume expansion of a gas at constant pressure is defined as the fraction of its volume at 0°C by which the volume of a fixed mass of gas expands per degree Celsius rise in temperature.

Answer 2

HERE IS UR ANSWER...

The coefficient of volume expansion (Υ) is defined as,

gamma equals= 1/V.dV/dT

ideal gas equation=pV=nRT

or

p=nRT/v

Substitute P in PT^2=constant to get

V=KT^3

for some constant kk. Differentiate second equation with respect to TT and substitute in first equation to get

Y=3/T

Which is volume expansion for gases.

Similarly After introducing the density of liquids we get Y = 2α for liquids.
