Question

During an all-night cram session, a student heats up a 0.403 liter (0.403 x 10- 3 m3) glass (Pyrex) beaker of cold coffee. Initially, the temperature is 15.6 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 98.9 °C. The coefficient of volume expansion of coffee is the same as that of water. How much coffee (in cubic meters) has spilled out of the beaker?

I've already posted this question once and was given the wrong solution, please help! Answer should be expressed in m^3.

Explanation / Answer

volume expansion coefficient of coffee=214*10^-6/k and volume expansion coefficient of glass =9*10^-6/k , now amount of coffee that is spilled is given by (214-9)*10^-6*(98.9-15.6) =0.01707 m^3
