# Thermal Conductivity of Brass

APPH12-NNG4GJ

A solid brass cylinder with a $16\text{ cm}$ diameter and $5.0 \text{ cm}$ length connects two heat reservoirs. One reservoir is kept at $100.0\text{°C}$ and the other at $0.0 \text{°C}$. In a $60\text{ second}$ period, $1.05\times {10}^{6} \text{ joules}$ of energy are transferred between the reservoirs.

Calculate the thermal conductivity of brass.

A

$0.023\cfrac { W }{ mK }$

B

$435\cfrac { W }{ mK }$

C

$6{,}500\cfrac { W }{ mK }$

D

$392{,}000 \cfrac { W }{ mK }$
