Lab: Calorimetry and Specific Heat

Question 1

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

Revolt · Accepted Answer

A: mass

Question 2

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

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

Question 3

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

Revolt · Accepted Answer

D: lead

Question 4

The buret clamp was used to stabilize the , and the beaker was used to stabilize the

Revolt · Accepted Answer

Selection 1: thermometer; Selection 2: calorimeter.

Question 5

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

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

Question 6

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