Would the tight packing of more insulation, such as glass wool, in an enclosed space increase or decrease the insulation value? Explain.
Burrito - yesAluminum foil - no.
try it and see what happensjust for a few secondsi left a fork in the microwave and nothing happened same thing with aluminum foilit depends on the microwave and the elements in the fork and aluminumjust do a trial but be prepared for a fire.
Putting aluminum foil in the microwave is recommended only for the 4th of July, if you you decide to use your old microwave as the centerpiece of the fireworks.
No aluminum foil or any other metal in the microwaveYou can use napkins, paper towels, wax paper or even a wet wash cloth can be wrapped around a burrito.
Beyond a certain point, it would decrease the insulation valueOne of the best insulators is airIt is nearly twice as insulating as glass woolThe only problem with air is that it will keep moving about! Hot air is less dense than cold air and tends to riseSo any heat it picks up tends to make it move away from a warm area, taking the heat energy with it, allowing cold air to take its place, and making it less effective as an insulatorGlass wool and similar loosely packed insulation materials trap the air in pockets and stop it moving about so muchIf you pack in too much insulation material, you are reducing the amount of trapped air and replacing it with material which is not as good as an insulator.
