1, water temperature rise:?
Initially, when a heat source acts on water, the water temperature begins to rise. This is because heat is transferred to water molecules, which makes them gain more energy and make the molecules move more violently.
2. Bubble formation:?
When the water temperature rises to 100 degrees Celsius (standard atmospheric pressure), water begins to boil. At this temperature, water molecules gain enough heat to overcome the attraction inside the liquid and convert it into gas. At this time, bubbles began to form in the water.
3. bubbles rise:?
The bubbles formed will rise because they are lighter than water. This is the boiling phenomenon we usually see, and bubbles rise from the bottom to the surface.
4. The water rolled:?
As more bubbles are produced, the water surface begins to stir and surge. This is because the formation and rise of bubbles will disturb the water surface.
5, the temperature is stable:?
When water boils, its temperature remains near the boiling point (100℃) until all liquid water is converted into steam. Even during the heating process, the temperature does not rise any more, because the excess heat is used to evaporate water.
6, water vapor release:
The boiling process will convert water molecules into water vapor and release it into the air. This is also the reason why water vapor Ran Ran rises in boiling water.
Matters needing attention when handling boiling water:
1, scald prevention:?
Boiling water is very hot, and contact with hot water will cause burns. When handling boiling water, please use appropriate protective measures, such as hot gloves or thick towels, to avoid burns.
2. Use a suitable container:?
Use containers suitable for heating water, such as kettle, pot or microwave oven safety container. Ensure that the container can withstand high temperature and avoid using fragile containers.
3. Be careful when pouring water:
Be careful when pouring boiling water into other containers or cups to avoid scalding or spilling. When dumping, the container should be stable to avoid water pouring out quickly.
4. Avoid steam burns:?
Boiling water will produce a lot of steam, so be careful not to put your hands, face or other parts near the steam to avoid burns.
5. avoid splashing hot water:?
Boiling water may spill when boiling, so be careful not to splash it on your skin. The container can be lightly covered with a lid, but it should not be completely closed to let the steam out.
