Answer:
(A) 800 K (B) 2.4 KW
Explanation:
We have given the COP =1.6
The sink temperature 
We have to find the source temperature, that is 
(A) We know that COP of the heat pump is given by 
So 
(B) We have given the work done =1.5 KW
The rate of heat transfer is given by 
Sugar, sucrose (C12H22O11: a disaccharide, composed of the two monosaccharides: glucose and fructose), is odorless, that is, it lacks odor. When heated a phase change occurs resulting in melting of a thick syrup.
