Difference between Thermal Diffusivity and Thermal Conductivity

Mar 2016
Hello everybody,

Maybe somebody can help me. I have to write a paper for my chemistry class.
Problem is I can't wrap my head around the concept of thermal diffusivity and thermal conductivity. In my mind it always sounds like the same?
I found an article online that presents the problem quite well, but I think I need somebody to explain it to me in layman terms.
Here is the article for reference http://www.linseis.com/en/our-products/thermal-diffusivity-thermal-conductivity/

Best regards,
