Children, even those that are vaccinated, may develop rotavirus disease more than once. That is because neither natural infection with rotavirus nor rotavirus vaccination provides full immunity (protection) from future infections. Usually a personâs first infection with rotavirus causes the most severe symptoms.
Because molecules move quicker at higher temperature, causing them to collides more. Since they collides more, reaction occurs to be a lot faster to. And that's why things dissolve quicker in hot water than in room temperature water.
Hot water will certainly evaporate faster, and produce a lot more condensation than cold water, and that's what we are seeing here. The water itself is not freezing, it's the evaporation (the steam) that is condensing and then freezing. So boiling water will produce more ice fog than cold water.
