Question
1. When a container is filled to the brim with liquid, what happens when the temperature rises? You are doing a controlled experiment on a strange, liquid metallic substance.
A glass flask has volume 1.0x10 -3 m3 at 0.0 0C and is completely filled (to the brim) with a strange, liquid metal at this temperature. The volume thermal expansion coefficient of glass is ?g = 1.7x10 -5 (oC) -1. When the flask and metal are warmed to 57.0 oC, some of the liquid metal overflows and the metal
Explanation / Answer
1. Expanded volume of glass = 1.7 x 10^-5 * 57 = 0.969x10^-3 m^3
Total volume = 1.969x10^-3 m^3
Expanded volume of metal = 18 x 10^-5 * 57 = 10.26 x 10^-3 m^3
Total volume = 11.26 x 10^-3 m^3
Volume Spill = 11.26 - 1.969 = 9.291x10^-3 = 9291 cm^3
2. a. Heat = Heat required to heat ice to 0 + heat required to change phase + heat required to heat water to 55
= 12*0.48*10 + 12*79.9 + 12*1*55 = 1676.4 cal
b. Heat = Heat required to heat ice to 0 + heat required to change 6 g to water
= 12*0.48*10 + 6*79.9 = 537 cal
