Definition: The spontaneous escaping of molecules of a liquid from their surface at any temperature is called evaporation. Evaporation Process: Most common question in this regard is, How does …
Why fish and plants survive underneath water in winter?
The lower density of ice than liquid water at 0°C compels water in ponds and lakes to freeze from surface to the downward direction. Water attains the temperature of 4°C by the fall of temperature in …

Why ice floats on water?
When the temperature of water is decreased and ice is formed then the molecules become more regular and this regularity extends throughout the whole structure. Empty spaces are left behind as shown in …
How Soap perform cleansing action?
Soaps and detergents perform the cleaning action because the polar parts of their molecules are water soluble due to hydrogen-bonding and non-polar parts remain outside water. …
Why H2O is liquid while H2S or H2Se are gases?
When we consider the hydrides of group VA, VIA, VIIA then NH3, HF and H2O show maximum boiling points in the respective series. The reason is the enhanced electronegative character of N, O and F. That …

How do Hydrogen Bonding Affect Solubility?
In addition to water, ethyl alcohol (C2H5OH) also has the tendency to form hydrogen bonds. So, ethyl alcohol can dissolve in water because both can form hydrogen bonds with each other. Similarly, …
