... Physics: Mechanisms of heat loss Aim: In this investigation, I intend to conduct an experiment involving the three mechanisms of heat loss - conduction, convection and radiation. I intend to discover which factor affects temperature the most, and which affects it the least. Plan: I will take 5 plastic cups, and cover each in different combinations of insulation (see fig. 1). I will heat water with a kettle, and pour carefully into the cups. Every minute I will take the temperature of each cup, for 20 minutes. To keep this a fair test, I must ensure that I begin the timer at the same temperature for each cup, that each cup is measured at equal intervals (1 every minute) and that the amount of water within each cup (15ml) is the same. Before beginning the real thing, I will check my equipment and methods by performing a preliminary experiment. This will also help me ensure
