Question

1 kg mass of liquid A at temperature 3 0 ∘ C and 2 kg mass of liquid B at 2 0 ∘ C are mixed in a calorimeter of negligible heat capacity. If final temperature of the mixture is 2 5 ∘ C . What will be the ratio of their specific heat capacity S B ​ S A ​ ​ ?

TestHub · Accepted Answer

Heat lost by A = Heat gained by B. m A ​ S A ​ Δ T A ​ = m B ​ S B ​ Δ T B ​ 1 ⋅ S A ​ ( 30 − 25 ) = 2 ⋅ S B ​ ( 25 − 20 ) 5 S A ​ = 10 S B ​ S A ​ / S B ​ = 2
