​Hydrogen Bond- a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Polar Covalent Bond- A covalent bond, also called a molecular bond, is a
​chemical 
bond that involves the sharing of electron pairs between atoms.

​Capillary action: Capillary action describes the spontaneous flow of a liquid into a narrow tube or porous material. This movement does not require the force of gravity to occur. In fact, it often acts in opposition to gravity.

Visible Range: 
The visible spectrum is the portion of theelectromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths from about 380 to 740 nanometers.
