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.
To find out if what temperature water will freeze the fastest. Secondly whether a lid over the water will increase the freezing process? Hypothesis: I think hotter water will freeze faster than the colder water. The freezing process will be slower with a lid covering the water. Background Research: Hotter water freezes faster than colder water in some circumstances. This phenomenon is called the Mpemba effect.
