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?

A
the material with the smallest specific heat
B
the material with the greatest specific heat
C
the material whose specific heat is farthest from the specific heat of the metal pan
D
the material whose specific heat is closest to the specific heat of the metal pan
6

However, compared to the other options, lead is too

A
expensive.
B
dangerous.
C
heavy.
D
dangerous and heavy.

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.

A
The metals were not heated to 100°C.
B
The metals were heated beyond 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.
F
Less metal was added to the calorimeter than was massed.
