Two liquids at temperature 60^@ C and 20...

Two liquids at temperature `60^@ C` and `20^@ C` respectively have masses in the ratio `3:4` their specific heat in the ratio `4:5`. If the two liquids are mixed, the resulatant temperature is.

A

`70^@ C`

B

`50^@ C`

C

`40^@C`

D

`35^@ C`

Text Solution

Verified by Experts

The correct Answer is:
D
Heat lost = Heat gained
`theta = (m_(1)S_(1)theta_(1)+m_(1)S_(2)theta_(2))/(m_(1)S_(1)+m_(2)S_(2))`.
