-John Yeah- Posted November 17, 2012 Report Share Posted November 17, 2012 I am doing a chemistry IA where I investigated the enthalpy change of displacement reactions (e.g. zinc powder and copper sulphate). The reaction occurred in a polystyrene cup with a lid. A hole was created for the thermometer to pass through and contact with the solution. I realized that some of the heat generated by the reaction is lost to surroundings with this setup. Is there any way that can minimize heat loss? I found something called "bomb calorimeter". It seems to be able to preserve heat very well but is it only used in combustion reactions?I am working on the evaluation part.Any suggestions?

Bernardo Silva Posted November 17, 2012 Report Share Posted November 17, 2012 Polystyrene insulation is the best way to go in a school context. Put the reactant beaker in 3 or 4 polystyrene cups if you have to. Reply Link to post Share on other sites More sharing options...
