# Draw the temperature versus distance graph

Hello, I have two materials with different thermal conductivity.

I am supposed to draw the temperature vs. distance graph between 23 K and 200K. I assume that in it is a linear decrease if you look at only one of the materials, but they have different slopes because of the different thermal conductivity properties? Is there a easy way to relate the slope to the thermal conductivities?

PS:

Later in the assignment I am supposed to calculate the temperatures where the materials meet. If I do this first, this would answer my question. But I am wondering if you can draw this without doing any calculations?

do you know have the definition of thermal conductivity is?

should be a big hint there if you write out the equation...

"should be a big hint there if you write out the equation... "

Thank you, this statement made me figure it out.
