Question

Which substance would retain the most heat for

Answer 1

The aluminium substances would retain the most heat for the longest period of time.

What is retaining heat?

Retaining of heat is the quantity of heat that a substance or medium can store over time or the amount of heat that a specific amount of that substance can hold in itself. Substances that store heat 'well' (for a long time) also require a long time to heat up.

Copper and aluminium have the highest thermal conductivity among the more common metals, whereas steel and bronze have the lowest. When determining the metal to utilise for a certain application, heat conductivity is a critical quality to consider.

In addition, potassium has the highest specific heat and the longest heat retention time. Polystyrene, a polymeric polymer, can retain heat for up to 11 hours. This implies it can hold heat for extended periods of time.

Hence the aluminium substances would retain the most heat for the longest period of time.
