In this experiment, you need to examine the idea of thermal energy transfer. Using a controlled experiment, what might a good question about the variables that affect thermal energy transfer be? Thermal energy transfer depends on many properties, but limit your question to only two.

Besides the amount of material, there is also another variable that is manipulated within each of the two mass groups and represented as three types. This independent variable is the .
In each case, the dependent variable, the one that you measure the response in, is the .

This part contains a known amount of water, which is placed there before the experiment starts.
Which statements are part of the safety protocol for this lab experiment? Check all that apply.Always wear a lab coat and safety goggles when performing an experiment.Use caution when freezing fluids as they may expand.Use the right gear, such as tongs and thermal mitts, to handle hot objects.Check glassware, such as beakers and flasks, for cracks and chips prior to use.Ear protection should be worn to protect against the loud noises associated with heat transfer.
The dependent variable, the one that you measure the response in, is the .
