Why does aluminium have a high specific heat capacity?
The SHC of aluminum will be higher than iron and copper, this is because the volume the less dense the meta lis, thus the higher the SHC because the metals contains big atoms which slowly heat up thus more energy is needed to make the molecules get hot and move around.
Which metal has highest specific heat capacity?
Thermal capacity is the amount of heat required to increase the temperature of an object by one degree. The following table provides the values of the thermal capacity of some of the metals and Aluminum. It shows that Aluminum has the highest thermal capacity.
Why does iron have a low specific heat capacity?
The heavier elements contain fewer atoms to absorb the energy per gram of material and therefore tend to have lower specific heat capacities.
Why does aluminum have a high specific heat capacity?
What does it mean when we say specific heat capacity of iron is 450 J kg * C?
Specific heat capacity in J / kg °C The greater the mass of the substance then the greater amount of energy needed to raise the temperature. For example a 5kg mass of iron would need 2250J (5 x 450J).
What is the specific heat capacity of iron in J kg C?

| Limestone | 806 | 806 |
Why does aluminum heat up faster?
This is because metals like aluminum are very good conductors of heat, so they absorb heat very quickly.
Does aluminum have a low specific heat?
After doing some research, I found that found that aluminum and air relatively low specific heats (https://www.engineeringtoolbox.com/specific-heat-capacity-d_391.html). This implies that aluminum and air have a low number of degrees of freedom.

Thermal capacity is the amount of heat required to increase the temperature of an object by one degree. The following table provides the values of the thermal capacity of some of the metals and Aluminum. It shows that Aluminum has the highest thermal capacity.
Is iron a good conductor of heat?
The reason it holds its heat so well is that cast iron is a relatively poor conductor of heat: one-third as good as aluminum and only one-fifth as good as copper.
How fast does iron heat?
