CHAPTER XXVI. 



ICE. 



Q. What is ICE ? 



A. FROZEN WATER. When the air 

 is reduced to 32 degrees of heat, water 

 will no longer remain in & fluid state. 



Q. WlllJ is SOLID ICE LIGHTER than WATER? 



A. Because water expands by freez- 

 ing ; and as the bulk is increased, the 

 gravity must be less. 



Nine cubic inches of water become ten when frozen. 



Q. Why do EWERS BREAK in a FROSTY NIGHT ? 



A. Because the water in them freezes; 

 and as the water is expanded by frost, 

 it bursts the ewers to make room for its 

 increased volume. 



Q. Why does it not expand UPWARDS ( like 

 boiling water}, and RUN OVER ? 



A. Because the surface is first frozen , 

 and the frozen surface acts as a plug, 

 which is more difficult to burst than the 

 earthen ewer itself.
