Question

One liter of mercury at 10⁰C is heated to 30⁰C. Find the increase in the volume of mercury. The coefficient of cubical expansion of mercury is 1.8 X 10^-4 0C^-1.

Answer 1

Volume of mercury, V = 1 liter Rise in temperature, t = 30 - 20 = 20°c Coefficient of volume expansion, y = 1.8 x 10^-4°C ^-1
Increase in volume = V x t x y
= 1 x 20 x 1.8 x 10^-4
= 3.6 x 10^-3 liter
