Explanation / Answer

Q1.

Aluminium has a heat capacity of approx 0.9 whereas eiron has 0.45

therefore, aluminium changes LESS temperature per unit mass

Q2.

Yes, it is known that aluminium is not that "metallic"

recall that metals have good conductivity + heat capacities

but aluminium has low heat capacity

It is actually used some time as wraping material in order to use it as a adiabatic/insulant material

Q3

stones have very low het capacities, they are composed of minerals, which contain plenty of nonmeltas,

therefore, low heat cpacity
