Your bedroom gets direct sunlight through a window during the hottest part of the day. you ask your mom to turn down the thermomstat in the house so your room can cool down. instead, your mom suggests that you put aluminum foil over the windows. 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. me! it would be greatly you so

Electroplating is a way to coat a complex metal object with a very thin (and hence inexpensive) layer of a precious metal, such as silver or gold. in essence the metal object is made the cathode of an electrolytic cell in which the precious metal cations are dissolved in aqueous solution. suppose a current of 480.ma is passed through an electroplating cell with an aqueous solution of agno3 in the cathode compartment for 46.0 seconds. calculate the mass of pure silver deposited on a metal object made into the cathode of the cell. round your answer to 3 significant digits. also, be sure your answer contains a unit symbol. ×10μ

The mini-refrigerator fire was most likely caused by what type of wiring?

6–48 bananas are to be cooled from 24 to 138c at a rate of 215 kg/h by a refrigeration system. the power input to the refrigerator is 1.4 kw. determine the rate of cooling, in kj/ min, and the cop of the refrigerator. the specific heat of banana above freezing is 3.35 kj/kg·8c.
