Abstract
			The Gradient in Steady State Heat Conduction
			
				Interactive exercises on temperature and heat flow and
				discussion of laboratory observations lead to the statement of
				the fundamental law of heat conduction
			 
			
				 
			Equation
				1  
			
				which relates the temperature distribution
				 
				and heat flux vector,
				 ,
				at a point in space.  The scalar proportionality factor,
				 ,
				is called the thermal conductivity. Several
				examples of steady state, one dimensional Cartesian and
				cylindrical heat flow, for constant and non-constant
				 ,
				provide practice in integration, solving simple ordinary
				differential equations and the physical understanding of real
				problems.
