Does it cost more time or money if I cook food in an aluminum pot or a Reverewar

Question

Does it cost more time or money if I cook food in an aluminum pot or a Reverewareâ (copper bottom) pot? The Al pot weighs 400. g; the Revereware pot is 200 g Cu and 250 g Al (the bottom is Cu-shown at right).

Does it cost more time or money if I bake brownies in a metal (Al) or glass (SiO2) pan? The Al pan weighs 200 g, and the glass pan weighs 1.00 kg.

1. a)Does it cost more time or money if I cook food in an aluminum pot or a Reverewareâ (copper bottom) pot? The Al pot weighs 400. g; the Revereware pot is 200 g Cu and 250 g Al (the bottom is Cu-shown at right).

b)Does it cost more time or money if I bake brownies in a metal (Al) or glass (SiO2) pan? The Al pan weighs 200 g, and the glass pan weighs 1.00 kg.

Heat capacities: SiO2 = 10.6 cal/mol×K, Cu = 5.480 cal/mol×K, Al = 5.82 cal/mol×K

Please explain thanks

Explanation / Answer

1) a)

if I cook food in an aluminum pot it takes more time but less cost.

if i cook food in Reverewareâ (copper bottom) pot it takes less time but more cost.

because in Reverewareâ pot has copper bottom so it gains heat very fast due to low specific heat.

where as in aluminum pot it takes more time to gain heat.

b)

if I bake brownies in a metal (Al) it takes less time and less cost.

if i bake brownies in a glass (SiO2) pan it takes more time and more cost.

because SiO2 is more cost than Al.
