Unit of Phase constant is Radians per metre .
nothing
The units for Rydberg's constant are [L-1].
Joules/K.mol
There is no constant relationship between units of length and units of angle.
The graph of y = c, a constant will be a straight line parallel to the x-axis and c units from it..
A change of phase takes place at a constant temperature.
nothing
Since volume is an extensive property, there is no particular constant associated with it - indeed, by virtue of being an extensive property, it is not constant unless the mass, temperature, pressure, phase, and composition remain constant. There are, of course, conversion factors between different volume units - and the conversion factors are constants.

Coherent sources are sources of light with a constant phase difference. The conditions for this are that there is a constant phase difference and that the light is of the same wavelength.
Most standard residential service is single phase. Therefore, I would say most all residential A/C units are single phase.
The units are m-1 or per metre.
The units for the gas constant of 0.0821 are liter-atmospheres/mole-Kelvin
Kc is the equilibrium constant and is the ratio of the activity of the reactants (numerator) to the activity of the product (denominator). The activity of each component is raised to the power of its corresponding chemical stoichiometric coefficient. Since the activity of each chemical is unitless, the equilibrium constant will also have no units. Example: For equilibrium of chemicals in the gas phase, each activity will be measured by its partial pressure (units of pressure) multiplied by its fugacity (units of 1/pressure), so the activity of each gas participating in the equilibrium will be unitless, and the corresponding ratio (Kc) will be unitless.
the acid ionization constant (Ka) has no units
The units for Rydberg's constant are [L-1].
