Properties Of Solids And Liquids Question 537

Question: The coefficient of apparent expansion of mercury in a glass vessel is $153 \times 10^{- 6} /^{\circ} C$ and in a steel vessel is $144 \times 10^{- 6} /^{\circ} C$ . If $α$ for steel is $12 \times 10^{- 6} /^{\circ} C,$ then that of glass is

Options:

A) $9 \times 10^{- 6} /^{\circ} C$

B) $6 \times 10^{- 6} /^{\circ} C$

C) $36 \times 10^{- 6} /^{\circ} C$

D) $27 \times 10^{- 6} /^{\circ} C$

Show Answer

Answer:

Correct Answer: A

Solution:

$γ_{r e a l} = γ_{a p p .} + γ_{v e s s e l}$ So ${(γ_{app .} + γ_{vessel})}_{glass} = {(γ_{app .} + γ_{vessel})}_{steel}$

$\Rightarrow 153 \times 1 0^{-6} + {(γ_{vessel})}_{glass} = {(144 \times 1 0^{-6} + γ_{vessel})}_{steel}$

$F u r t h e r, {(γ_{v e s s e l})}_{s t e e l} = 3 α = 3 \times (12 \times 10^{- 6}) = 36 \times 10^{- 6} /^{\circ} C$

$\Rightarrow 153 \times 10^{- 6} + {(γ_{v e s e e l})}_{g l a s s} = {(144 \times 10^{- 6} + γ_{v e s s e l})}_{s t e e l}$

$\Rightarrow {(γ_{v e s s e l})}_{g l a s s} = 3 α = 27 \times 10^{- 6} + 36 \times 10^{- 6}$

$\Rightarrow α = 9 \times 10^{- 6} /^{\circ} C$
