Using the data, explain which material would be BEST to include in the lunchbox.
A
The best material to use is rubber, since it is the best conductor. A conductor will help increase the transfer of heat from inside of the lunchbox to outside of the lunchbox.
B
The best material to use is rubber, since it is the best insulator. An insulator will help slow the transfer of heat from outside of the lunchbox to inside of the lunchbox.
C
The best material to use is foam, since it is the best conductor. A conductor will help increase the transfer of heat from inside of the lunchbox to outside of the lunchbox.
D
The best material to use is foam, since it is the best insulator. An insulator will help slow the transfer of heat from outside of the lunchbox to inside of the lunchbox.
