Expert Answer
The coefficient of volume expansion (Υ) is defined as,
ideal gas equation, 
or 
or Substitute P in PT2=constant ; to get - 
for some constant kk. Differentiate second equation with respect to TT and substitute in first equation to get 
Which is volume expansion for gases.
for some constant kk. Differentiate second equation with respect to TT and substitute in first equation to get Which is volume expansion for gases.Similarly After introducing the density of liquids we get Y = 2α for liquids.
Note : Topic Related to higher grade physics Thermodynamics topic.
