Properties Of Solids And Liquids Question 400

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 a for steel is $12 \times 10^{- 6} /^{\circ} C$ , then that of glass is

Options:

A) $

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

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

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

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $γ_{r e a l} = γ_{a p p .} + γ_{v e s s e l}$ So ${(γ_{a p p .} + γ_{v e s s e l})}_{g l a s s} = {(γ_{a p p} + γ_{v e s s e l})}_{s t e e l}$

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

$= 144 \times 1 0^{- 6} + {(γ_{v e s s e l})}_{s t e e l}$

$F u r t h e r {(γ_{v e s s e l})}_{s t e e l} = 3 α = 3 \times (12 \times 1 0^{- 6})$

$= 36 \times 10^{- 6} /^{o} C$

$\Rightarrow 153 \times 1 0^{- 6} + {(γ_{v e s s e l})}_{g l a s s}$

$= 144 \times 1 0^{- 6} + 36 \times l 0^{- 6}$

${(γ_{v e s s e l})}_{g I a s s} = 3 α = 27 \times 10 /^{o} C$

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