How to solve heating curve problems
WebIn the equation, you only need to put the change in degrees C or the change in degrees K not the actual temperature itself. A change of 1c is the same as a change of 1K (273K=0C, 274=1C, 275=2C, etc.). Hope this makes sense. ( 68 votes) Flag Show more... Nathan Vaska 11 years ago Why is the heat of fusion so much less than the heat of vaporization? WebThis example shows how to solve the heat equation with a temperature-dependent thermal conductivity. The example shows an idealized thermal analysis of a rectangular block with a rectangular cavity in the center. The partial differential equation for transient conduction heat transfer is: ρ C p ∂ T ∂ t - ∇ ⋅ ( k ∇ T) = f. where T is ...
