1 mol of gas at STP {Ans: 22.4 L}Standard Conditions {Ans: T: 25 C or 187 K P: 1 atm Concentration: 1M}Bond Energy {Ans: Energy required to break a bond by separating its components in to their isolated, gaseous, atomic states.}Pascal's Principle {Ans: a change in pressure applied to an enclosed fluid will be transmitted undiminished to every portion of the fluid and to the walls of the vessel. (Think of a piston) P = F1 / A1 = F2 / A2 A1d1 = A2d2 W = F1d1 = F2d2 A: area of piston to which the force is being applied d: distance the fluid increases/decreases on each side}Focal Length {Ans: =r/2 Lenses and Mirrors}Snell's Law {Ans: n1sinθ1 = n2sinθ2 n2>n1 light bends toward normal n1>n2 light bends away from normal}
