The opposite faces of a metal plate of 0.2 cm thickness are at a difference of temperature of `100^@C`and the area of the plate is 200 sq cm. Find the quantity of heat that will flow through the plate in one minute if
K=0.2 CGS units.

Explanation

K=0.2 CGS units
A=200 sq cm.
d=0.2 cm
`(theta_1-theta_2)=100^@C`
t=60 sec.
`Q=(KA(theta_1-theta_2)t)/d`
`=(0.2xx200xx100xx60)/(0.2)=12xx10^5` Cal
