by God to be an exception to a very 

 general rule) contracts till it is reduced 

 to 42 degrees, and then it expands till it 

 freezes. 



(Water freezes at 32.) 



Q. WHY does water expand when it 

 freezes ? 



A. Because it is converted into solid 

 crystals, which do not fit close, like the 

 particles of water. 



Q. Why is the water at the BOTTOM of a river 



NEVEE FROZEN ? 



A. Because when water is colder than 

 42 degrees, it instantly ascends to the 

 surface; and (if it freezes) floats there 

 till it is melted. 



(When a river is frozen, the water below the surface 

 is never less than 42.) 



Q. Show the WISDOM of GOD in this wonderful 

 exception to a general law. 



A. If ice were heavier than water, it 

 would sink; and a river would soon 

 become a solid block of ice, which could 

 never be dissolved. 



Q. Why does not the cold ICE on the SURFACE 

 of a river CHILL the water BENEATH, and make it 

 freeze ?
