Why does the level of water seem to not rise when salt is dissolved in water? Why does cold water hold more salt? How can surface runoff affect the water quality? Why is it hard to clean up water pollution? Why are solids hard?
We know that hot water is less dense than cold water–you observe this with heat rising. As such, the other hypothesis says hot water has a greater temperature gradient as it freezes. Since it’s hotter, and hot stuff rises, the temperature of the hot water sample will be less uniform ...
As water is cooled from 4c to 0c, what happens to its density? How does thermal stratification influence organisms? How does the depth of a lake affect its temperature? Why does cold water hold more salt? How does temperature affect the rate of transpiration? How does increased atmospheric ...
For example, other factors may influence the absence of relation such as the body surface evaporation59, the efficiency of oxygen extraction54, the effi- ciency of renal mechanism for water conservation60, as well as the lung structure57. Further studies may address the role of the maxillo...
A reading of 100 percent relative humidity means that the air is totally saturated with water vapor and cannot hold any more, creating the possibility of rain. Jose Luis Raota/Getty Images If you've ever been to places with humid climates, like southern Arkansas on a hot July day, you'...
Chinese and U.S. scientists have been working to create a SARS vaccine, but research has been made difficult by an absence of active disease to test treatments against. Research has been based around monoclonal antibodies, which hold promise as future diagnostic tools for SARS infection and treat...
the density of the maxilloturbinal within the nasal chamber does not seem associated with species living in arid or cold habitats48. When species are obliged to face harsh thermal or water-stress conditions and do not resort to torpor to avoid them, they may have to rely on a well-develop...

If you’re growing delicate plants like spinach or basil, make sure your water parameters (pH, dissolved oxygen) are stable. Size of System: Larger fish, like catfish, will need more space and produce more waste, which in turn supports larger-scale plant production. Consider the scale of ...
Alcohol is a tannin-based stain. You should use a standard laundry detergent to remove alcohol stains. If this doesn't work, you may try an oxygen-based bleach if allowed by the garments care label. You should usecold water to remove alcohol stainson clothes. ...
