The values of C (heat capacity) and density should be those of copper, not of air. The question and answer should read "thermophysical properties of copper".

[@kamurudeenka461]

Superb explanation. Very easy to understand.

hello Professor don't we have to check the biot number for this problem if not can you please explain why? because when i checked the biot number it is greater than .1 Bi=(hLc/K)=(20*50.025)/360 =2.77916 which is greater than 0.1 (Lc = volume /surface area= .07854/.001570=50.025)

load of peas at a temperature of 25°C is to be cooled down in a room at a constant air temperature of 1°C.
(a) How long the peas will rquire to cool down to 2°C when the surface heat transfer coefficient of the peas
is 5.81 W/m2 K? (b) What is the temperature
of the peas after a lapse of 10 min from the start of cooling?
(c) What air temperature must be used if the peas were to be cooled down to 5°C in 30 min? The peas are
supposed to have an average diameter of 8 mm. Their density is 750 kg/m3 and specific heat 3.35 kJ/kg K.
