Coefficient of volume expansion of some liquids(a/˚C)
Alcohol=1.1x〖10〗^(-4)
Glycerin=5.0x〖10〗^(-4)
Water=3.7x〖10〗^(-4)
Ether=1.63x〖10〗^(-4)
Mercury= 1.1x〖10〗^(-4
What is the increase in volume of 0.3m cube of ethyl alcohol when heated from 15˚C to 20˚C?

  1. Henry

    Increase = a(T-To)Vo =
    1.63*10^-4(20-15)0.3=2.45*10^-4 m^3.
