The image below is of an aluminium plate that will be heated
from the bottom. If the temperature at the bottom of the plate is
600 degrees Celsius and 20 degrees at the top, how long will it
take for the top of the plate to reach 200 degrees Celsius?
Thermal conductivity = 200 W/mK
Specific heat = 921.096 J/kgK
mass of plate = 70kg
