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 
Adaptation is the characteristic of an organism that allows it to survive better in an environment
Hello there.

Hey there!
No of hybrid orbitals , H = ( V +S - C + A ) / 2
Where H = no . of hybrid orbitals
V = Valence of the central atom = 5
S = No . of single valency atoms = 4
C = No . of cations = 1
A = No . of anions = 0
For PCl4 +
Plug the values we get H = ( 5+4-1+0) / 2
H = 4 ---> sp3 hybridization
sp3 hybrid orbitals are used by phosphorous in the PCl4+ cations
Answer C
Hope that helps!
