प्रश्न
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.
उत्तर
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
