Properties Of Solids And Liquids Question 486
The real coefficient of volume expansion of glycerine is 0.000597 per°C and linear coefficient of expansion of glass is 0.000009 per°C. Then the apparent volume coefficient of expansion of glycerine is 0.000597 - 3×0.000009 [AIIMS 2000]
Options:
A) 0.000558 per°C
B) 0.00057 per°C
C) 0.00027 per°C
D) 0.00066 per°C
Show Answer
Answer:
Correct Answer: B
Solution:
As we know $ {\gamma _{\text{real}}}={\gamma _{\text{app}\text{.}}}+{\gamma _{\text{vessel}}} $ therefore $ {\gamma _{\text{app}\text{.}}}={\gamma _{\text{real}}}-{\gamma _{\text{vessel}}} $
$ =0.000597-0.000027=0.00057/{}^\circ C $
