Properties of Air at 1 atm Pressure 
Properties of air For ideal gases, the properties cρ, k, µ, and Pr are independent of pressure. The properties ρ, ν, and α at a pressure P (in atm) other than 1 atm are determined by multiplying the values of ρ at the given temperature by P and by dividing v and α by P. 

Specific Gravity Table Chart and Equation

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.
