Solution:
In the freezer ice will form from water at 0oC Since the water is at 36oC, so the temp. required to fall will be 36oC - 0oC = 36o.
In the freezer temp falls @ 2oC at every 5 mins.
The temp. to fall 2o time taken = 5 mins.
Then the temp. to fall 36o the time taken = 5 / 2 x 36 mins = 5 x 18 mins - 90 mins = 1 hr 30 mins.
Ans: 1 hr. 30 mins.

Dear Student,
Please find the attached solution.
In the freezer ice will form from water at 0 degree C Since the water is at 38 degree C, so the temp. required to fall will be 38 degree C - 0 degree C = 38 degree
In the freezer temp falls at 3 degree C at every 4 mins.
The temp. to fall 3 degree time taken = 4 mins.
Then the temp. to fall 38 degree the time taken = 4 / 3 x 38 mins = 51 mins (approz) =
Hope this information will clear ur doubt
