As we know that water at 0 degree is converted into ice at 0 degree
So here heat is removed from it and it is given as
Q =mL
now we know that
m = 10 kg
L = 3.35 * 10^5 j/kg

now we have
Q = 10(3.35 * 10^5)
Q2= 3.35 * 10^5 J
now we know that COP of refrigerator is given as
Q2/w = T2/(T1-T2)
W = 3.31* 10^5 J
