The specific heat capacity of LEAD is 0.1276 J/g°C and the specific heat capacity of COPPER is 0.3845 J/g°C.

If both metals are heated for 1 minute, what will be true about the final temperatures of the two metals?

• The two metals will be the same temperature.

• The temperature of LEAD will be LOWER because LEAD has a lower specific heat capacity

• The temperature of LEAD will be HIGHER because LEAD has a lower specific heat capacity.

• Can not be determined from the information given.
