One of the reasons a microwave oven gets hot while in operation is because of hot air blown through the cavity (the cooking area). The magnetron (the microwave generating device) gets hot in operation, and a fan blows air through the cooling fins of this special device to keep it cool. That air gets hot, and is forced through the cavity to exit the oven on a side opposite that where it is drawn in. And the heated air heats the appliance itself.
No, they are mostly heated by the food they contain as the food heats up.
The microwave spins while heating food to ensure that the food is heated evenly on all sides, helping to prevent hot spots and cold spots in the food.
Breast milk should not be microwaved because it can destroy important nutrients and proteins in the milk, as well as create hot spots that can burn a baby's mouth. It is safer to warm breast milk by placing the container in warm water instead.
Cold spots in microwaves can occur due to uneven distribution of microwaves inside the appliance. This can be caused by factors such as the shape of the food being heated or the positioning of the food in relation to the microwave's rotating plate. To minimize cold spots, it is recommended to stir or rearrange the food halfway through the cooking process.
To keep cold food cold or hot food hot. Styrofoam is very good insulation.
Well, it they were in cold spots, the lava could/would freeze. So if they're in hot/warm places they're fine.
To keep cold food cold or hot food hot. Styrofoam is very good insulation.
No its not. If you like cold food better than hot food that's fine. Its your opinion. :)
Only if the water is too hot.
Cold food should be kept at 40 degrees or lower. Keep hot foods hot. This will insure safe food to eat.
Sunspots are very hot, just not quite as hot as the rest of the sun. Sunspots are cooler because the hot plasma is prevented from rising.
Keep hot foods hot, and keep cold foods cold.
