Merely heating a volume of water will only have a minuscule effect on the weight of the water.
Heating the water will however cause it to expand and thus have a lower density. (You have the same mass of water, but over a larger volume.)
No, the experiment does not show that cold water boils faster than hot water.
Cold water with high salinity
The hot can in cold water experiment results in the can collapsing due to the rapid cooling of the air inside, creating a vacuum that crushes the can.
Ice is lighter than the water it displaces .
Hot water need less energy to be evaporated than cold water.
bcoz cold water has no vapours n hot water has hot water vapours which dries faster n bcomes lighter than cold water
i thank on cold it has lighter forse then hot i thank i dont know the right anwser
I just did an experiment on this actually. Water molecules travel faster in hot water than in cold water. When food dye is added into hot water where the molecules are traveling faster, it mixes faster. In cold water, the particles are not traveling as fast and the food dye does not spread as fast.
Cold water is used to stop the process of photosynthesis in a leaf. This helps to fix any starch that has been produced in the leaf during the experiment. The cold water also makes the leaf more brittle, making it easier to handle during further steps of the experiment.
When a hot soda can is placed in cold water in the hot soda can in cold water experiment, the can undergoes a rapid cooling process. This causes the air inside the can to contract, creating a lower pressure inside the can compared to the outside. As a result, the higher pressure outside the can pushes the can inward, causing it to crush or implode.
The key findings from the ice water experiment are that the body's response to cold water immersion includes increased heart rate, blood pressure, and shivering to maintain core body temperature. Additionally, the experiment showed that the body can adapt to cold exposure over time, leading to decreased physiological responses.
Hot water. Hot water can also dissolve slightly more sugar than cold water can.
