The normalization condition that the trace of be equal to 1 defines the partition function to be () = (). If the number of particles involved in the system is itself not certain, then a grand canonical ensemble can be applied, where the states summed over to make the density matrix are drawn from a Fock space .

ρ (Greek letter rho) is the fluid mass density (e.g. in kg/m 3), and; u is the flow speed in m/s. It can be thought of as the fluid's kinetic energy per unit volume. For incompressible flow, the dynamic pressure of a fluid is the difference between its total pressure and static pressure. From Bernoulli's law, dynamic pressure is given by
Rhodium oxide can be produced via several routes: Treating RhCl 3 with oxygen at high temperatures. [3]Rh metal powder is fused with potassium hydrogen sulfate.Adding sodium hydroxide results in hydrated rhodium oxide, which upon heating converts to Rh 2 O 3.
Rho factor, a bacterial protein; Rho family of GTPases, including RhoA, RhoB, and RhoC; Rhodopsin, a protein encoded by the RHO gene; ρ, reaction constant in the Hammett equation in chemistry; ρ, measures sensitivity to the interest rate in finance
rho: mass density usually simply called density kilogram per cubic meter (kg/m 3) volume charge density: coulomb per cubic meter (C/m 3) resistivity: ohm meter (Ω⋅m) sigma: summation operator area charge density: coulomb per square meter (C/m 2) electrical conductivity: siemens per meter (S/m) normal stress: pascal (Pa)
Rhodium is a chemical element; it has symbol Rh and atomic number 45. It is a very rare, silvery-white, hard, corrosion-resistant transition metal. It is a noble metal and a member of the platinum group. It has only one naturally occurring isotope, which is 103 Rh.
Rho (/ ˈ r oʊ /; uppercase Ρ, lowercase ρ or ϱ; Greek: ρο or ρω) is the seventeenth letter of the Greek alphabet. In the system of Greek numerals it has a value of 100. It is derived from Phoenician letter res .
