Question

It is observed that 56.40 mL of water at 20∘C completely fills a container to the brim. When the container and the water are heated to 60∘C, 0.35 g of water is lost. Part A What is the coefficient of volume expansion of the container? Density of water at 60 ∘C is 0.98324 g/mL.

Answer 1

SOLUTION :

The water volume lost in terms of

V _lost = d V _W - d V _C  

= ( _W - _C ) V _o d T

= 0.356 m L

  _C = _W - V _lost / V _o d T

= 210 X 10^-6 - 0.356 / 56.4 X 40

_C = 210 X 10^-6 - 0.356 / 2256

  _C = 5.22 X 10^-5 /^o C
