Two liquids of masses `m` and `5 m` at temperatures `3 theta, 4 theta` are mixed, If their specific heats are `2S,3S` respectively, the resultant temperature of mixture is

A

`(66)/(17) theta`

B

`(55)/(17) theta`

C

`(44)/(17)theta`

D

`(33)/(17) theta`

Text Solution

Verified by Experts

The correct Answer is:
A
From principle of calorimetry
`theta = (m_(1)S_(1)theta_(1)+m_(2)S_(2)theta_(2))/(m_(1)S_(1)+m_2S_(2))`.
