Properties Of Solids And Liquids Question 490
Question: If on heating liquid through 80°C, the mass expelled is (1/100)th of mass still remaining, the coefficient of apparent expansion of liquid is [RPMT 2004]
Options:
A) 1.25 ´ 10?4/°C
B) 12.5 ´ 10?4/°C
C) 1.25 ´ 10?5/°C
D) None of these
Show Answer
Answer:
Correct Answer: A
Solution:
$ {\gamma _{\text{app}\text{.}}}=\frac{\text{Mass expelled}}{\text{Mass remained}\times \Delta T} $
$ =\frac{x/100}{x\times 80}=\frac{1}{8000}=1.25\times {{10}^{-4}}/{}^\circ C $
