A liquid of mass m and specific heat c is heated to a temperature 2T. Another liquid of mass m/2 and specific heat 2 c is heated to a temperature T. If these two liquids are mixed, the resulting temperature of the mixture is

A

`(2//3)T`

B

`(8//5)T`

C

`(3//5)T`

D

`(3//2)T`

Text Solution

Verified by Experts

The correct Answer is:
D
From principle of calorimetry ,
`theta = (m_(1)S_(1)theta_(1)+m_(2)S_(2)theta_(2))/(m_(1)S_(1)+m_(2)S_(2))`.
