Abstract
The problem of heat transfer in a solid, whose conductivity and specific heat depend on the temperature, is converted by a simple change of variable to one in which the conductivity may be held constant, and only the specific-heat term varies with temperature in a way which depends upon the variation of both parameters. The method is illustrated by application to a problem previously solved by Dusinberre in a different way. The effect on the final solution of different finite approximations to the derivatives is also discussed.Keywords
