Frying pans are good conductors of heat. a scientist developed four new materials to be used for making frying pans. he made rods of equal mass and length from each material. he tested their heat conductivity by exposing one end of each rod to the same amount of heat over the same duration of time. he measured the temperature change at the other end of the rod. the data he collected is shown in the table below.

based on the data collected, select the name of the substance that would make the best frying pan.

original temperature final temperature
material a 20°c 27°c
material b 20°c 37°c
material c 20°c 21°c
material d 20°c 35°c

Material B

Explanation:

The substance that would make the best frying pan is the one with the highest temperature at the end of the experiment because that means is the best conductor of heat, which is a desirable property in frying pans. In consequence, material B with a final temperature of 37 °C would make the best frying pan.

Only the final temperature is considered because all the other variables (mass, length, heat received, elapsed time) are equal to every rod.

explanation:

the atomic radius of a chemical element is a measure of the size of its atoms, usually the mean or typical distance from the center of the nucleus to the boundary of the surrounding shells of electrons.
