Q1. During an all-night cram session, a student heats up a one-half liter (0.50 x 103 m3) glass (Pyrex) beaker of cold coffee. At first, the temperature is 18 °C, and the beaker is filled to the brim. A short time later when the student returns, the temperature has risen to 92 °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?
