Every time I do this I am amazed at how close we get to 6000K. Of course, the nature of Stefan's Law helps and all the errors and assumptions seem to cancel each other out.
Admittedly, I have always done this experiment in either Thailand or Vietnam where it is rather sunny, but it might work well on a summer&'s day in UK.
Today, we put a cylindrical (8.3cm high x 4.4cm diameter) 1kg copper calorimetry block out in the sun for 6 minutes and it&';s temperature rose from 34 to 39 C. Plug these numbers into the attached worksheet and we get a surface temp of 5900K
Something went wrong, please try again later.
Just tried this in Qatar as an introduction lesson for my inherited Year 13 class as a fun ice-breaker lesson. We got around 5600K and the pupils really enjoyed to lesson, it never worked for me in the UK but I will most definitely use this again in the sunny climate of Qatar. Thanks for sharing!
