Question

A specific gravity bottle weighs 40g when empty and 1040g when filled with mercury at 0°C on heating to 100°C 10g of mercury over flows. If the coefficient of real expansion of mercury 0.0002/°C . Then the coefficient of volume expansion of glass​

Answer 1

Answer:

I don't know sorry sorry

Answer 2

Explanation:

Coefficient of real expansion, γreal=γapparent+γgγreal=γapparent+γg

[Math Processing Error]

⇒γα=1000−990990×(100)⇒γα=1000-990990×(100)

⇒γα=0.01×10−2/∘C⇒γα=0.01×10-2/∘C

∴γglass=γreal−γapparent=0.0002−0.0001=0.0001/∘C
