Question

A pan made of which substance would require the largest amount of heat for equal cooking?

Aluminum ( c = 0.22 cal/gC^o)

Gold ( c = 0.03 cal/gC^o)

Tin ( c = 0.054 cal/gC^o)

Copper ( c = 0.093 cal/gC^o)

Silver ( c = 0.056 cal/gC^o)

Answer 1

For equal coocking temperature of each pan should be same.

Suppose Initial and final temperature of each pan were and .

Heat required to raise the temperature of a substance from to is-

So required heat energy is proportional to the specific heat capacity of substance.

Since in the given values Aluminum has highest specific heat capacity,so a pan made of Aluminium will require largest amoumt of heat for equal cooking.
