Question

A glass vessel of volume 256 cm3 is just filled with
mercury at 20°C. How much mercury will overflow
when the temperature is raised to 100°C? Given:
αglass = 4 x 10^-6 °C^-1 and Ymercury = 1.8 x 10^-4°C^-1​

Answer 1

Explanation:

Given A glass vessel of volume 256 cm^3 is just filled with mercury at 20°C. How much mercury will overflow  when the temperature is raised to 100°C?

The increase in volume of glass vessel will be

So ΔV glass = β glass Vo Δ T

                    = 4 x 10^-6 x 256 (100 – 20)

                    = 4 x 10 ^-6 x 256 x 80

                    = 0.0819 cm^3  

Now the increase in volume of mercury will be

So Δ V mercury = β mercury Vo Δ T

                          = 1.8 x 10^- 4 x 256 (100 – 20)

                          = 3.6864 cm^3

The volume of mercury that overflows will be  

So ΔV mercury – ΔV glass = 3.6864 cm^3 – 0.0819 cm^3

                                           = 3.6045 cm^3  

Answer 2

Answer:

The amount of mercury that overflow when the flask is heated to 800C (Coefficient of volume expansion of glass is 27×10-6/0C,γ of mercury .. TQ Mark as brainlist
