Why does a solid change to liquid when heat is added? Why is temperature an intensive property? Why does ice melt faster in water? Why do ionic compounds dissolve readily in water? Why is the volume of an ice cube is greater compared to when it melts to form liquid water?
A visual way to explain density is by examining a floating object. Ice or a piece of cork floats in a glass of water. You can start by asking your audience to consider why some objects float and other objects sink. The answer, of course, is density. Gravity pulls on all objects, and...
Explain why it is important to determine the Rh of a pregnant woman? What are the consequences of a tubal pregnancy? Why does water expand when it freezes? Give an explanation on why ice floats. Why do spontaneous abortions occur?
CMRis the GSL trend associated with contemporary mass redistribution resulting from changes in land ice mass and terrestrial water storage (Fig.2a).SDis the trend in sterodynamic sea-level (see Gregory et al.35for extended definition) that encompasses both global-mean steric changes and regional ...
Alcohol and water, which have polar molecules, make particularly good dielectrics.Sponsored linksHow cloud capacitors cause lightning When clouds drift through the sky, ice particles inside them rub against the air and gain static electrical charges—in just the same way that a balloon gets charged...
