CANDLE FLAME. 75 



parts of carbon and hydrogen ; and the 

 hydrogen of the tallow, combining with 

 the oxygen oj the air, produces flame. 



Q. Why is the FLAME of a candle HOT ? 



A.. 1st Because the flame liberates 

 latent heat from the air and tallow : and 



2ndly It throws into rapid motion the 

 atoms of matter. 



Q. How is LATEST HEAT liberated by the 

 flame of a CANDLE ? 



A. When the hydrogen of the tallow 

 and oxygen of the air combine, they 

 condense into water ; and much of their 

 latent heat is squeezed out. 



Q. How are the ATOMS of MATTER disturbed 

 by the flame of a candle ? 



A. 1st When the hydrogen of the 

 tallow and oxygen of the air condense 

 into water, a vacuum is made ; and the 

 air is disturbed, as a pond would be, if a 

 pail of water were taken out. 



2ndly When the carbon of tallow and 

 oxygen of the air expand into carbonic 

 acid gas, the air is again disturbed ; in a 

 similar way as by the explosion of 

 gunpowder.
