Brass requires more energy than silver
Aluminum requires more energy than copper
Aluminum requires more energy than brass
Explanation:
The specific heat capacity of a substance indicates the amount of heat energy required to raise 1 kg of that substance by 1 degree in temperature.
Mathematically:
where
Q is the heat supplied to the substance
m is the mass of the substance
is the change in temperature
Therefore, the higher the specific heat capacity of a substance, the more energy is needed to increase its temperature.
Here we can compare the specific heat capacity of the materials mentioned:
Silver:
Brass:
Platinum:
Aluminium:
Copper:
Therefore, the correct statements are:
Brass requires more energy than silver
Aluminum requires more energy than copper
Aluminum requires more energy than brass
