Boiling water at `100^@C` and cold water at `t^@C` are mixed in the ratio `1 : 3` and the resultant maximum temperature was `37^@ C`. Assuming no heat losses, the value of 't' is

A

`4^@C`

B

`9^@C`

C

`12^@C`

D

`16^@C`

Text Solution

Verified by Experts

The correct Answer is:
D
Heat lost by hot water = Heat gained by cold water.
`m_(1)S_(1) xx Delta theta_(1) = m_(2)S_(2) Delta theta_(2) (Given,(m_(1))/(m_(2))=(1)/(3))`.
