see below

Explanation:

It depends by the specific heat of the two metals #880 J/(Kg xx K) #for Al and #130J/(Kg xx K) # for Pb . Specific heat is generally lower when the MM of the element is highter.
When a substance has a small specific heat (cp)it heats quickly because the heat providedit is #Q= m cp Delta T# where you see that the heating (#Delta T#) is inversely proportional to the specific heat (cp) if the mass (m) is the same
