subjected to a colder one. Research Question: How does the surface area to volume ratio affect heat loss in organisms? Hypothesis: I hypothesize that the larger the surface area to volume ratio‚ the more heat will be lost and vice versa. In this experiment‚ there will be a series of sizes of round bottom flasks‚ each having a different surface area to volume ratio. The smallest round bottom flask will have the biggest surface area to volume ratio‚ therefore the heat loss in that particular

Investigation of how Changing the Volume of Water in a Container Affects Its Rate of Heat Loss Aim : To investigate how changing the volume of water in a container affects its rate of its heat loss. The variable of this investigation is the volume of water which is put in the container. What I already know: I already know that the larger the volume of water there is the less heat loss occurs. I can tell this from my previous pilot experiment where I investigated‚ if the volume of water in a
