The coefficient of volume expansion of glycerine is \(49 \times 10^{-5} \mathrm{~K}^{-1}\). The percentage change in its density for a \(50^{\circ} \mathrm{C}\) rise in temperature is
- A 4.25
- B 5.24
- C 3.54
- D 2.45
Answer & Solution
Correct Answer
(D) 2.45
Step-by-step Solution
Detailed explanation
The density \(\rho\) of a liquid at temperature \(T\) is related to its density \(\rho_0\) at initial temperature \(T_0\) by the relation \(\rho = \dfrac{\rho_0}{1 + \gamma \Delta T}\), where \(\gamma\) is the coefficient of volume expansion and \(\Delta T\) is the change in…
