Two beakers `A` and `B` contain liquids of mases `300 g` and `420 g` respectively and specific heats `0.8 cal//g-.^(0) C` and `0.6 cal//g-.^(0) C`. The amount of heat on them is equal. If they are joined by a metal rod

A

heat flows from the beaker `B` to `A`

B

heat flows from `A` to `B`

C

not heat flows

D

heat flows neither from `A` to `B` not `B` to `A`.

Text Solution

Verified by Experts

The correct Answer is:
B
Quanity of heat on `A` = Quanity of heat on `B`
`m_(A) xx S_(A) xx theta_(1) = m_(B) xx S_(B) xx theta_(2) rArr theta_(1) gt theta_(2)`.
