Question

A glass flask of volume 500cm3 is just filled with mercury at 0°c. how much mercury overflows when the temperature of the system is raised to 80°c?​

Answer 1

Answer:

0.72cm^3 of mercury will over flow

Explanation:

Using the formula for volumetric expansion of a liquid

∆V= Vo*B*(T2-T1)

Where

∆V= change in volume= unknown

Vo= initial volume=0.5L

T1= initial temperature= 0°C

T2= final temperature= 80°C

B= the coefficient of volumetric expansion of mercury= 1.80X10^-4/°C

∆V= 0.5*1.80x10^-4*80. = 7.2x10^-4L

or

0.72cm^3 of mercury overflow
