Question

Explain why a mass of lead heats up more quickly than an equal mass of aluminium?

Answer 1

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
