Three liquids A, B and C are at temperatures of 60 ∘ C , 55 ∘ C and 50 ∘ C respectively. 4 g of A mixed with 3 g of C gives 55 ∘ C and 2 g of A mixed with 3 g of B gives 57 ∘ C . The temperature of th

Question

Three liquids A, B and C are at temperatures of 60 ∘ C , 55 ∘ C and 50 ∘ C respectively. 4 g of A mixed with 3 g of C gives 55 ∘ C and 2 g of A mixed with 3 g of B gives 57 ∘ C . The temperature of the mixture when equal masses of B and C are mixed is

TestHub · Accepted Answer

4 c A ​ ( 60 − 55 ) = 3 c C ​ ( 55 − 50 ) 4 c A ​ = 3 c C ​ 2 c A ​ ( 60 − 57 ) = 3 c B ​ ( 57 − 55 ) c A ​ = c B ​ 3 ( 55 − T ) = 4 ( T − 50 ) T = 7 365 ​ ≈ 52.1 ∘ C
