Bob Posted February 27, 2011 Report Share Posted February 27, 2011 Ok so I am assigned with a design lab and the only requirement is that it should be related to heat capacity.I would say I have understood everything needed for thermal physics (I am doing SL) but I am stuck with no idea where to go...I have heard that a good physics lab should have 'qualitative data'; like you can establish a relationship from a series of numeric data;but it seems that the only possibility is a 'quantitative' lab about heat capacity - the heat capacity/ heat loss of different materials, etc.I just need an idea and I think I am alright; I need one that is easy to write and carry out... argh this is really a hassle to me, I am not a very creative person... any help is appreciated Reply Link to post Share on other sites More sharing options...
Sublime Sunshine Posted February 27, 2011 Report Share Posted February 27, 2011 Why don't you try and test the specific heat capacities of different materials (metals perhaps)? Reply Link to post Share on other sites More sharing options...

Sublime Sunshine Posted February 27, 2011 Report Share Posted February 27, 2011 The specific heat capacity of a substance shouldn't change (in general). If you were looking for the effect of X on Y sort of an experiment, why not try something like, how does the amount of thermal energy transfered affect the magnitude of the change in temperature when heating a particular substance (should be linear).
