Molecules of carbon dioxide must absorb heat energy to change from solid to gas. Warm water contains more heat energy than cold water.
Hot water has the energy(heat) to make the change go faster
No, the process of cold water heating up to its boiling point is a physical change rather than a chemical change. This is because the molecules in water remain the same during the transition from liquid to gas; only their arrangement and energy levels change.
It melts faster in cold
Cold water.
Cold water will freeze faster. Because the freezing point of water is 0oC, water that is closer to that point will freeze faster then hot water. This is because it will require less time to lower the temperature to the freezing point.
Hot Water
Water boils faster when it is warm rather than cold. This is because warm water is closer to its boiling point, so it requires less energy to reach that point compared to cold water.

cold water faster
In hot water the water molecules are moving at a faster rate than they move in cold water. The faster moving molecules hit the salt molecules with greater force and knock them away from the other salt molecules faster. That way the salt molecules dissolve in the water quicker.
cold water
The temperature of the room you put the water in.
No, hot water heats up faster than cold water.
No, hot water heats up faster than cold water.
hot water has faster moving particales than cold water
Ice cubes don't faster in cold water because the temparature of cold water is low, ice cubes melt faster in high temparature.
