Two identical bowls of casserole need to be kept warm. The cook covers bowl 1 with transparent plastic wrap and bowl 2 with shiny aluminum foil, in each case trapping a layer of air between the covering and the casserole.
After a few minutes, will the temperature of casserole 1 be greater than, less than, or equal to the temperature of casserole 2?
Choose the best explanation from among the following:
In each case heat loss by convection is suppressed, so the final temperatures will be the same.
The lower thermal conductivity of the plastic wrap over casserole 1 will suppress heat loss by conduction better than aluminum foil.
The high reflectivity of the aluminum foil over casserole 2 will suppress heat loss by radiation, while the heat losses by conduction and convection for casseroles 1 and 2 will be similar.

The high reflectivity of the aluminum foil over casserole 2 will reduce heat loss by radiation, while heat losses by conduction and convection will be similar for casseroles 1 and 2.

What are the main reasons?

I. Because plastic wrap has a lower thermal conductivity than aluminum foil, it will prevent heat loss by conduction better.

II. Because heat loss by convection is reduced in each case, the final temperatures are the same.

III. The high reflectivity of the aluminum foil over casserole 2 will reduce heat loss by radiation, while heat losses by conduction and convection will be similar for casseroles 1 and 2.

How heat loss affect the bowls?

Heat loss by convection is suppressed in each case, so the final temperatures are the same.

Because plastic wrap has a lower thermal conductivity than aluminum foil, it will prevent heat loss by conduction better.

The high reflectivity of the aluminum foil over casserole 2 will reduce heat loss by radiation, while heat losses by conduction and convection will be similar for casseroles 1 and 2.
