Answer to Question #294027 in Physics for percy

Question

250 mL of ethyl alcohol is placed in a Pyrex glass to the brim at 0°C. How much is the expansion of ethyl alcohol after heating it to 50°C? the expansion of glass? Will the ethyl alcohol overflow? (β of ethyl alcohol is 100 X 10-6 / °C and of Pyrex glass is 3.2 10-6 / °C)

Answer 1

$$\Delta V_e=V_0\beta_e \Delta T=1.25\text{ mL},\\ \Delta V_g=V_0\beta_g \Delta T=0.04\text{mL}.\\ \Delta V_e>\Delta V_g.$$

The ethyl alcohol will overflow.
