When the same masses are heated by the same amount, which of the following substances will heat up the slowest?
-aluminum....0.90
-iron.............0.46
-gold..............0.13
-copper.........0.39
When the same masses are heated by the same amount copper will heat up the fastest. Copper is a good conductor of heat that is why it easily heats up. Gold is not a good conductor of heat because of its stable properties.
