A thermos flask is designed with double-walled insulation to minimize heat transfer. The vacuum between the walls prevents heat from escaping through conduction or convection. Additionally, the reflective surface on the inner wall reduces heat loss through radiation. This combination of insulation techniques helps hot water stay hot for a long time in a thermos flask.
The water will eventually evaporate, leaving a dry, empty glass. Any Impurities or dust in the original water will remain as a slight staining on the glass. If the glass of water had stood in bright sunlight, algae may have formed, making any staining greenish in colour.
Spent fuel rods are stored in pools of water because they continue to generate heat and radiation after being removed from the reactor. The water acts as a shield to absorb radiation and helps to cool the fuel rods. This method ensures the safe handling and storage of the radioactive material.
Boiling water does not affect the hardness of water. Hardness in water is caused by minerals like calcium and magnesium, which remain in the water even after boiling.
Water does not decompose in an electric kettle. The water will heat up and either evaporate into steam or remain as liquid water.
The water balloons will remain intact but will reach the same temperature as the cooler. If the cooler is cold, the water balloons will also be cold. If the cooler is warm, the water balloons will also be warm.
Sperm can survive in water for a short period of time, but they tend to die quickly due to the lack of nutrients and temperature fluctuations. The sperm's ability to swim and fertilize an egg decreases in water, making it unlikely for them to remain alive for an extended period.
Pond if it's largr enough and puddle if it's small/Most ponds are more durable than puddles and last for a considerable period of time or permanently.
The chemical structure of water remain unchanged.
The chemical nature of water remain unchanged.
This water remain as a liquid.
This water remain as a liquid.
This water remain as a liquid.
waterdoes not remain still in sea
Water remain water -H2O.
This water remain as a liquid.
Ultrapure water is obtained.
a cockroach dies when it remain in water for sometime as it cannot swim and thus it drowns and dies
