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.
Answer by Carlos Ayala. Confidence votes 1.5K. When you wish to dissolve a solid in a liquid faster, you increase the temperature. This makes the solid particles move faster and farther, and thus dissolve in the liquid faster.However, the problem with dissolving a gas is the opposite: gas particles already are moving fast and far, to the point where it is difficult to keep them stay in the liquid. The opposite is thus done, lower the temperature.nswer by Carlos Ayala. Confidence votes 1.5K. When you wish to dissolve a solid in a liquid faster, you increase the temperature.
