▪ First, you measured the ✔ massweightdensityvolume of the metal and the water inside the calorimeter.

▪ Then, you shined✔ heatedmelteddissolved the metal and added it to water in the calorimeter.

▪ After heat transferred from the metal to the water, you measured the density✔ temperature changevolume specific heat of both materials.

You computed the specific heat for each of the four metals using the formula below: C metal equals StartFraction negative C water m water delta T water over m metal delta T metal EndFraction. Check all items that you used, either directly or indirectly, each time you did this computation.

Considering only specific heat, aluminumcopperiron✔ lead would be the most ideal for use in cookware.

However, compared to the other options, lead is too expensive.dangerous.heavy.✔ dangerous and heavy.

Considering everything, ✔ aluminumcopper or

✔ ironlead, would make the best cookware and therefore may be the best choices overall.

The buret clamp was used to stabilize the buretcalorimetertemperature✔ thermometer, and the beaker was used to

stabilize the beaker.✔ calorimeter.temperature.thermometer.

Why did you use two coffee cups during the experiment instead of just one cup?

A student who did the same experiment that you did determined the specific heat for all of the metals. His values were all 0.10 to 0.20 less than the actual specific heat values. Select all possible sources of this error listed below.

Based on the table above, olive✔ sesamevegetablesoybeancorn oil would transfer heat the best because its specific heat is

the ✔ lowest.highest.closest to 2.00.

Now you need to put handles on your cookware! You have five different options, including metals and nonmetals such as wood. Based on specific heat, which material would be the best choice?
