If metal is left unexposed in a microwave oven, the metal will deflect the microwaves and cause sparks. However, if it is submerged in water, the microwaves dissipate and are absorbed by the liquid. In turn, the water is heated.
When batteries are submerged in water, the water can cause a short circuit, leading to the battery overheating, leaking, or even exploding. This can be dangerous and should be avoided.
When a balloon is submerged in cold water, the air inside the balloon cools and contracts, leading to a decrease in volume. This causes the balloon to shrink in size.
When a battery is submerged in water, it can cause a short circuit, leading to the release of harmful chemicals and potentially causing the battery to overheat, leak, or even explode. It is important to avoid submerging batteries in water to prevent these dangerous outcomes.
When an object is immersed in water, it means it is completely surrounded or covered by the water.
The air gets trapped, and if the glass is brought deep enough under the water the air will be pressurised and will take up less space.
Putting a non-metal plate in the microwave and pouring water on it is generally safe as long as the plate is microwave-safe. However, pouring water on a very hot plate can cause the water to boil rapidly, potentially leading to splattering or steam burns. It's best to let the plate cool down before adding water.
Nothing. It just sinks.

To make noodles in the microwave, place the noodles in a microwave-safe bowl and add water until the noodles are submerged. Microwave on high for 2-4 minutes, stirring halfway through. Check for doneness and drain any excess water before serving.
When batteries are submerged in water, the water can cause a short circuit, leading to the battery overheating, leaking, or even exploding. This can be dangerous and should be avoided.
If the water is at standard temperature and pressure (25 degrees Celsius and one atmosphere), the water has density of 1 kilogram per liter. When submerged, the metal displaces its own volume of water. Therefore, the volume of the metal is 1 liter, and the density of the metal is 6 kg/liter.
No, you should not put a metal stem in water and then place it in the microwave oven. Metal can cause sparks and potentially start a fire in the microwave, as it reflects microwaves instead of absorbing them. This can damage the microwave and pose safety hazards. It's best to use microwave-safe materials, such as glass or certain plastics, for heating food or liquids.
To cook instant noodles in the microwave, place the noodles in a microwave-safe bowl, add water until the noodles are submerged, and microwave on high for 2-3 minutes. Stir the noodles and let them sit for a few minutes before eating.
If the metal can be submerged, put it in an ice water bath using pure water to maintain 0 C. To keep it at 50 C, you could use a constant temperature bath. If the metal can not be submerged, you might need a temperature controlled chamber.
When a balloon is submerged in cold water, the air inside the balloon cools and contracts, leading to a decrease in volume. This causes the balloon to shrink in size.
To withstand high water pressure when they are submerged at sea.
Only if the grating is submerged under a couple of inches of water.
