Lab: Calorimetry and Specific Heat

Question 1

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

Revolt · Accepted Answer

mass; Selection 1: mass; Selection 2: heated; Selection 3: temperature change

Question 2

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

Revolt · Accepted Answer

heated

Question 3

▪ After heat transferred from the metal to the water, you measured the of both materials.

Revolt · Accepted Answer

temperature change

Question 4

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

Revolt · Accepted Answer

iron

Question 5

You computed the specific heat for each of the four metals using the formula below: Check all items that you used, either directly or indirectly, each time you did this computation.

Revolt · Accepted Answer

the first law of thermodynamics (heat lost by a metal equals the heat gained by the water); the ability of heat to flow from a hot object to a cooler one; masses for the metal and the water in the calorimeter; temperature changes for the water and the metal; the known specific heat of the water

Question 6

Select question 817f3cec

Revolt · Accepted Answer

lead

Question 7

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

Revolt · Accepted Answer

thermometer; Selection 1: thermometer; Selection 2: calorimeter.

Question 8

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.

Revolt · Accepted Answer

The metals were not heated to 100°C.; The metals cooled before they were added to the water.; The thermometer was not completely submerged in the water while reading.; The calorimeter was not sealed properly, so heat escaped.

Question 9

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

Revolt · Accepted Answer

sesame; oil would transfer heat the best because its specific heat is: sesame; lowest.

Question 10

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?

Revolt · Accepted Answer

the material with the greatest specific heat
