Question

10 litres of hot water at 70°C is mixed with
an equal volume of cold water at 20°C.
Find the resultant temperature of the water.
(Specific heat of water = 4200 J/kg -K)​

Answer 1

Answer:

M1 = M2 = 10L or 10kg

S1 = S2 = 4200J/kg/k (S stands for Specific heat of water)

T1 = 70°

T2= 20°
