Achemist places a 100 g cube of each of the metals listed in the table on a separate hot plate. all of the hot plates are identical. each hot plate is set on medium heat, and all of the cubes have the same initial temperature. based on the specific heat values in the table, rank the metals in terms of how quickly they will reach the target temperature of 80°c. use "1" to indicate the fastest and "5" to indicate the slowest.

From the metals given in the table, the ranking on how quickly they reach the target temperature from 1 5 is: Pb, Sn, Cu, Fe, Al.

Specific heat can be defined as the amount of heat required to raise the temperature of 1 unit of mass by 1-degree celsius.

The specific heat can be calculated as:

where Q is the heat energy required

m is the mass of the object

c is the specific heat capacity, and

is the change in temperature.

In the given condition the five sets have the same mass and same change in temperature. Thus m and c are constant for all five sets.

So, the relationship between specific heat and heat energy is directly proportional.

The lower the specific heat, the more heat energy will be required to raise the temperature.

Thus, for the metals given in the table, the ranking on how quickly they reach the target temperature from 1 5 is: Pb, Sn, Cu, Fe, Al.
