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.
Less water left behind means less water to freeze.**. **Problem: Even accounting for evaporation, hot water has been observed to freeze faster than cold. Theory: Hot water creates convection patterns in the air inside a freezer, which increases its cooling efficiency.***. ***Problem: You can run an experiment with hot and cold trays in the same freezer and still observe the warm one to freeze faster than the cool one.
