A liquid of mass M and specific heat S i...

A liquid of mass `M` and specific heat `S` is at a temperature `2T`. Another liquid of thermal capacity `1.5 times` the first liquid at a temperature `(T)/(3)` is added to it. The resultant temperature of the mixture will be

A

`(4)/(3) t`

B

`t`

C

`(t)/(2)`

D

`(2)/(3) t`

Text Solution

Verified by Experts

The correct Answer is:
B
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))`
`(Given, m_(2)S_(2) = 1.5 xx m_(1)S_(1))`.
