Leidenfrost effect 
The Leidenfrost effect is a phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly. 

Resultant Vector Physics 
A resultant is a single vector which represents the combined effect of two or more othervectors (called components). The components can be determined either graphicallyor by using trigonometry. 

Vector Quantities Physics 
A vector quantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities.
