Yes. I can't find anything wrong with using a microwave to slightly heat up cold water for fish, esp. tropical (warm-water) fish like Bettas. Just make sure to check the temperature with a thermometer and stick to the ideal 70-80-degree range. I'm less sure about heating "treated" water in a microwave (which can contain many varieties of conditioners, medications, etc.), but at the very least treat the water many hours in advance.
By getting a fish tank heater.
The microwave rays heat it.
It would be more accurate to say that microwaves can be converted to heat. A microwave oven is designed speicifically to heat water, or anything that contains water.
At microwave frequency, water molocules resonate, creating heat.
The best way to safely microwave a hot water bottle is to heat the water in a separate microwave safe container in the microwave and then put the microwaved, hot water into the water bottle.
microwave it
Micro waves heat by vibrating the conductive molecules in items. Pure water (which has no impurities) does Not boil in a microwave oven. It does get extremely hot! Be care and use the recommended time for that your microwave states for water.
Water and density, they will cook from the inside out if you microwave them.
because it makes the water taste bad and it is a haven for germs and bacteria to grow
Microwave ovens primarily heat water (they can heat metal as well, although that is not their purpose), therefore food must contain some moisture in order to be heated in a microwave oven. Dried food will not heat well.
Absolutely, the bottom of the microwave is heat and water resistant.
When food is placed inside the microwave oven, the microwave released will 'agitate' the water molecules in the food, which causes heat to be produced, which then cooks the food.
I think a hot bottle of water cause how are you supposed to heat up a brick.not a microwave cause a microwave use water to heat things up a brick does NOT have water in it
