The idea is simple - drop a chunk of dry ice in some water; it will bubble and smoke. In practice, this is a little more difficult, because the dry ice will cool down the surrounding water and start to form a shell around itself of water-ice. Eventually the smoking and bubbling stops. The only way to keep this from happening is to keep the water hot, which increases the rate at which the dry ice is consumed. That's why dry ice isn't really used as often as people think it is.
When smoke touches cold water in a test tube, it cools down rapidly, causing the smoke particles and gases to condense and form a visible cloud. This cloud is the result of the water vapor in the smoke condensing into tiny water droplets, making the smoke more visible.
Hot water can extinguish fires more effectively than cold water because it has a higher energy content, which allows it to heat up the fuel source more quickly and potentially reach the flash point faster. The heat from hot water can also help to break down the fuel source more rapidly, making it more difficult for the fire to continue burning.
Hot water will make sugar dissolve faster compared to cold water because the increased temperature causes the sugar molecules to move more rapidly and interact with the water molecules more effectively.
cold ocean water is more dense than warm water
Yes, warmer water will make the plastic comb more flexible and easier to bend compared to cold water, which will make the comb more rigid and resistant to bending. This is because the heat from the warm water softens the plastic material, allowing it to be reshaped more easily.

stand in cold water everyday and increase it a bit more everyday
Cold water is more refreshing than warm water because it can help lower your body temperature quickly, which can make you feel more alert and rejuvenated. The cold temperature of the water can also help to constrict blood vessels, which can make you feel more awake and refreshed.
Hot water will make sugar dissolve faster compared to cold water because the increased temperature causes the sugar molecules to move more rapidly and interact with the water molecules more effectively.
Cold water is more dense.
cold ocean water is more dense than warm water
Yes, hot water has more thermal energy than cold water because its molecules are moving faster and have higher kinetic energy. This increased molecular motion results in higher temperature and thermal energy content in hot water compared to cold water.
Neither can make smoke. Smoke is made from the burning of an object without the right amount of oxygen to burn properly. Cold air or hor air if introduced to the opposite temperature can make water vapor.
Yes, warmer water will make the plastic comb more flexible and easier to bend compared to cold water, which will make the comb more rigid and resistant to bending. This is because the heat from the warm water softens the plastic material, allowing it to be reshaped more easily.
no the only diffence is the dye in the fuel that does not make the fuel smoke more. water levels in the fuel will so it can vary from the different places that the fuel is purchased from.
hot water contains more energy than cold water. cold water causes the water molegules to vibrate more.
