The densities of two substances are 2 3 ...

The densities of two substances are 2 3 and their specific heats are 0.12 and 0.09 respectively. What is the ratio of their thermal capacities per unit volume ?

A

`8:9`

B

`9:8`

C

`4:3`

D

`3:4`

Text Solution

Verified by Experts

The correct Answer is:
A
Here thermal Capacity/Vol. `="Density "xx "Sp."` heat
`therefore ("Th. Capacity/unit vol. of I")/("Th. Capacity/unit vol. of II")=(2xx0.12)/(3xx0.09)=(8)/(9)`
`therefore` Correct choice is (a).
