Which of the following substances could be heated from 20°C to 100°C most quickly?
Assume identical heat sources are used on all substances.
Gold
Platinum
Silver
Tin
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.
For a skillet, used for cooking, do you want a high or low specific heat
High, so that it will need more energy to heat up
Low, so that it will change temperature quickly
