Question

which are potential sources of error in the experiment? check all that apply. estimating temperature to the nearest tenth of a degree estimating the mass of the sample to the nearest tenth of a gram estimating the thickness of the foam cups the position of the cups of sand and water under the heat lamp the brand of light bulb used for the heat lamp the air temperature outside the lab

Explanation:

Estimating measurements like temperature and mass can introduce human - error. The position of cups under the heat lamp can affect heat distribution, the brand of light bulb can vary in heat output, and outside air temperature can influence the lab environment. Estimating the thickness of foam cups is usually not a significant source of error in most experiments related to heat transfer with sand and water samples.

Answer:

estimating temperature to the nearest tenth of a degree, estimating the mass of the sample to the nearest tenth of a gram, the position of the cups of sand and water under the heat lamp, the brand of light bulb used for the heat lamp, the air temperature outside the lab
