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.
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 fas â¦ ter.enry's law states that the solubility of a gas is directly proportional to the partial pressure of that gas over the liquid. The higher the partial pressure, the more gas will be dissolved-- that's why your blood boils in a vacuum; there's not enough pressure to keep the gas in it dissolved.
