Three different substances have the specific heats in the ratio `1:2 : 3` and the temperature increases in the ratio `3 : 2 : 1` when the same heat is supplied to the three substances. The ratio of their masses is

A

`1 : 1: 1`

B

`1 : 2 : 3`

C

`3 : 2 : 1`

D

`4 : 3 : 4`

Text Solution

Verified by Experts

The correct Answer is:
D
`Q = mS(Delta theta) = const rArr (m_(1))/(m_(2)) = (S_(2))/(S_(1)) xx (Delta theta_(2))/(Delta theta_(1))`.
