Question

Your bedroom gets direct sunlight through a window during the hottest times of the day. you ask your mom to turn down the thermostat in the house so your room can cool down. instead, your mom suggests that you put aluminum foil over the window. what will the results be if you take your mom's advice?

a. a room cooled by minimizing heat transfer by reflection b. a room cooled by minimizing heat transfer by radiation c. a room cooled by minimizing heat transfer by convection d. a room cooled by minimizing heat transfer by conduction 10 points... Please help!!!

Answer 1

If you take your mom's advice, a. the room will be cooled by minimizing heat transfer by reflection.

The Sun is heating your room by its radiation.

The aluminium foil is shiny, so it reflects the Sun’s radiation back outside the window.

Convection is the transfer of heat caused by the air moving around in your room.

Conduction occurs only when a hot object is in contact with a cooler object.
