SUGGESTED WORK 



There is an interesting experiment which you 

 may like to try. Take a clay pipe, fill the bowl with 

 powdered soft coal. Cover the bowl with a mixture 

 of plaster of paris and water. Hold the bowl over 

 the flame of a spirit lamp or gas jet and make it hot. 

 You can easily construct a support of sticks and 

 wire for holding the pipe in place, as it will become 

 too hot to hold with the hand. After the bowl 



has become hot, hold a 

 lighted match near the 

 end of the pipe-stem. 

 Observe what happens. 

 What does this prove ? 

 If you perform this 

 experiment write an 

 account of it, telling all 

 you do, what occurs, 

 and what this shows 



Wlicre coal is used 



you.
