A2 Appendix A
The water potential will be equal to the solute potential of a solution in an open container, since the pressure potential of the solution in an open container is zero. the Solute Potential of the Solution
i = ionization constant (For sucrose this is 1.0 because sucrose does not ionize in water.) C = molar concentration R = pressure constant (R = 0.0831 liter bars/mole K) T = temperature in Kelvin (273 + ºC)
rate dY/dt Population growth dN/dt=B-D exponential growth
logistic growth
dY= amount of change t = time B = birth rate D = death rate N = population size K = carrying capacity rmax = maximum per capita growth rate of population
temperature coefficient q 10
Primary Productivity calculation
t 2 = higher temperature t 1 = lower temperature k 2 = metabolic rate at t 2 k 1 = metabolic rate at t 1 Q 10 = the factor by which the reaction rate increases when the temperature is raised by ten degrees SurfAce AreA And VoluMe (^) dilution – used to create a dilute solution from a concentrated stock solution
i = initial (starting) C = concentration of solute f = final (desired) V = volume of solution

Surface Area of a Sphere
Surface Area of a cube
Surface Area of a rectangular Solid
r = radius l = length h = height w = width A = surface area V = volume
a = surface area of one side of the cube gibbs free energy ΔG = ΔH – TΔS ΔG = change in Gibbs free energy ΔS = change in entropy ΔH = change in enthalpy T= absolute temperature (in Kelvin) ph = – log [H+]
