Criteriod D- The factors affecting the temperature change in a copper calorimeter

Grade 10 : Experiment - Factors affecting heat rise in a liquid

Background studies:

The chemistry of the hydrocarbons.

Instructions:

investigate one factor that affects the temperature rise in a can of water when heated using a spirit burner

Main objectives:

To isolate and identify the variables involved in an experiment and to investigate the effect of changing one of these variables

Assessment: Criterion D: Experimental procedures Maximum 6
