Objects A and B that are initially separ...

Objects `A` and `B` that are initially separated from each other and well isolated from their surroundings are then brought into thermal contact. Initially `T_(A) = 0^(@)C` and `T_(B) = 100^(@)C` . The specific heat of `A` is less than the specific heat of `B`. After some time, the system comes to an equilibrium state. the final temperatures are:

A

`T_(A) = T_(B) gt 50^(@)C`

B

`T_(A)gt T_(B)gt 50^(@)C`

C

`T_(A) = T_(B) lt 50^(@)C`

D

`T_(B)gtT_(A) gt 50^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A
At equilibrium `T_(A) = T_(B)`
