This is a most difficult problem, even for a 4th year engineering student and an unfair question to give a student not versed in calculus. The problem is not solvable as stated since they have not mentioned the size of the plate or where on the plate the temperature is measured. The temperature distribution is found by doing a transient heat transfer analysis of a "point source" using conductivity and diffusivity of the metal. If he is just a youngster in grade school, I don't think his teacher could "solve" the problem. Of the list, the one with the smallest thermal conductivity would heat up the fastest near the source but would be cooler, away. Copper, having the highest conductivity would be hotter away from the source and cooler near it. By the way, you shouldn't do your son's homework in the first place. What happens when he is working as an engineer later in life. Will he call you up for answers?

"By the way, you shouldn't do your son's homework in the first place." Ditto Zekeman!! I commend MaMa Kay for being an involved parent, however prodding, supervising, hinting and encouraging worked just fine for my kids when they where in school. The greatest skill I learned in school and life was to take the intiative and figure things out myself. Modified by Kelly Bramble at Wed, Nov 29, 2006, 08:11:59

I agree and I probably was a bit too harsh with mamakay. I just hope that she encourages and not attempts to do the work or the most valuable assets she can instill- initiative,inquisitiveness,creativity and drive will be lost. Our country needs all the great scientists we can get and maybe he can help solve some of the most challenging technological problems of our time-- like alternative sources of energy, clean combustiion processes, and nuclear waste product disposal that have plagued us for too long.
