Question

a glass vessel is completely filled with 340gm of mercury at 0°C. what weight of the mercury will overflow when the vessel is heated to 100°C?

Answer 1

$\huge\underline\blue{\rm Answer:}$

$\red{\boxed{\sf Weight\:of\:expanded\:volume=0.061N }}$

$\huge\underline\blue{\rm Solution:}$

$\large\underline\pink{\sf Given: }$

• Mass (m) = 340 g

• Heated to Temperature = 100°C

$\large\underline\pink{\sf To\:Find: }$

• Weight of mercury will overflow when vessel is Heater to 100°C = ?

━━━━━━━━━━━━━━━━━━━━━━━━━

As per first condition :

${\boxed{\rm Volume\:of\:Hg={\frac{Mass\:of\:Hg}{Density\:of\:Hg}}}}$

$\large\implies{\sf {\frac{340}{13.6}} }$

$\large\implies{\sf Volume\:of\:Hg=25mL}$

As per Second condition :

$\implies{\sf Expanded\:Volume= 25mL×100°C×182×10^{-6}mL/°C}$

$\large{\sf Expanded\: Volume=0.455mL}$

_________________________________

$\large{\sf Mass=Volume×Density}$

$\large\implies{\sf 0.455×13.6}$

$\large\implies{\sf m= 6.19g}$

________________________________

Weight of expanded Volume :

$\large{\boxed{\sf Mass\:Hg=m×a}}$

$\large\implies{\sf 0.00619×9.8}$

$\large\implies{\sf 0.061N }$
