Question

Practice Problems 5:
1. A solid of mass 150 g at 200°C is placed in 0.4 kg of water at 20°C till a constant temperature
is attained. If the S.H.C. of the solid is 0.5 J/g K, find the resulting temperature of the
mixture​

Answer 1

Answer:

27.7°C Approx

ms∆T = MS∆T

m = 150g

s = 0.5/4.2

∆T= 200-T

M - 400gram

S - 1

∆T - T -20
