Two liquids are at temperatures `20^@C and 40^@C`. When same mass of both of them is mixed, the temperature of the mixture is `32^@C`. What is the ratio of their specific heats?

A

`1//3`

B

`2//5`

C

`3//2`

D

`2//3`

Text Solution

Verified by Experts

The correct Answer is:
D
`Q_1 = Q_2`
`:. ms_1 (32 -20) = ms_2 (40 - 32)`
`s_1/s_2 = 8/12 = 2/3. `
