Question

thermometer has it rise inside a sealed tube as T increases. Practice Problem 14.4 Part A -Practice Problem: In this example we will compare the volume expansion of a liquid with the volume expansion of the vessel that holds the liquid. A glass flask with a vclume of 200 cm is filled to the brim with mercury at 20 °C. When the temperature of the system is raised to 100 °C, does the mercury overflow the flask? If so, by how much? The coefficient of volume expansion of the glass is 1.2 × 10-5 K-1 Coefficients of volume expansion (K i) Material Solias Quartz (fused) Invar Glass Sleel Copper Brass 0.12 × 10-5 0.27× 10 s 1.2-2.7x 105 3.6 10 5.1 × 10-5 6.0 x 10- 7.2 × 10-5 Liquids Mercury Glycerin Ethanol Carbon disulfide 18 × 10-s 49 × 10 s 75 × 10-5 115 × 10-5 Suppose we replace the mercury with carbon disulfide. How much carbon disulfide runs over the flask? Express your answer in cubic centimenters to three significant figures.

Explanation / Answer

new volume of glass flask =0.0002 m^3 + 1.2 x 10^ -5 (0.0002 m^3) (353.15 K) =0.00020084756 m^3= 200.84756 cm^^3 apprx

new volume of mercury = 0.0002 m^3 + 18 x 10^ -5 (0.0002 m^3) (353.15 K)= 212.7134 cm^2

mercury will outflow by =  212.7134 -  200.84756 =11.86584 cm^3 apprx
