Answer: Final temperature = 206∘C
Explanation:
 Heat Energy is given as   
 q= mCΔT 
 ehere 
q= Heat energy = 87.4J
m= mass=1.25g
C=specific heat c= 0.386Jg∘C) , 
 ΔT =  Change in temperate of which the final temperature= 25.0∘C
  q= mCΔT 
 ΔT = q/mC
ΔT = 87.4/ 1.25 X 0.386=181.14∘C
But, 
 T final- T initial = ΔT
T final = T initial + ΔT
 T final = 25.0∘C +181.14∘C=206.14∘C rounded to 206∘C
 
        
             
        
        
        
Given :
Length , l = 59.8 m.
Breadth , b  = 26.6 m.
Depth , d = 3.7 ft .
Density of water ,  .
 .
To Find :
Mass of water in pool .
Solution :
First we will covert depth into m from ft .

For ,
 
So , volume of pool is :

We know , density is given by :

So , 
Putting given values in above equation :

Hence , this is the required solution.
