On a warm summer day in Helsinki, the temperature is 20°C and the relative humidity is 40%. What is the absolute humidity? Numbe
r kg/ kg Dry Air What is the humid volume of the air? Number m/kg Dry Air What is the specific enthalpy of the air, taking H20 (L, 0°C, 1 atm) as a reference state?
For the resolution of these questions, it necessary to get the information from the well known humidity charts that allow us to accurately and quickly know all the values required for being able to use these values in other more specific procedures, then the values obtained are getting as:
When cells of Elodea are placed in a salt solution the phenomenon of plasmolysis occurs and the water will start to move out from the cell.
