Answer:
The specific heat capacity of quartz is 0.71 J/g°C.
Explanation:
Heat lost by quartz will be equal to heat gained by the water

Mass of quartz= 
Specific heat capacity of quartz= 
Initial temperature of the quartz= 
Final temperature = 

Mass of water=
Specific heat capacity of water= 
Initial temperature of the water = 
Final temperature of water = 



On substituting all values:

we get:

The specific heat capacity of quartz is 0.71 J/g°C.
Answer:
Molecules make scents. Aromatic ones (That is, containing rings of carbon atoms with delocalised electrons). Some unpleasant smells are due to hydrogen and sulphur groups.
