a) show that for a solid steam, it behaves like an ideal gas, the sublimation curve has the form P = -B / T + A where A and B are constants. b) For Mg at 700k, B 7527. Calculate the heat of sublimation of Mg at this temperature in cal / mol. c) Is the equation deduced in a) useful to determine the sublimation curve?

The ideal gas law PV=nRT relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant Requals 0.08206 L⋅atm/(K⋅mol) or 8.3145 J/(K⋅mol). The equation can be rearranged as follows to solve for n: n=PVRT This equation is useful when dealing with gaseous reactions because stoichiometric calculations involve mole ratios.

The van der Waals equation of state is (P + a(n/V )^2)(V/n − b) = RT, where a and b are gas-specific constants. For Hydrogen gas, a = 2.45 × 10^-2P a · m^6 and b = 26.61 × 10^-6m^3/mol, while for an ideal gas a = b = 0. (a) Consider trying to measure the ideal gas constant in a lab from the relation R = P V/(nT), where P, V, n, and T are all measured parameters. However,...

Carbon dioxide (CO2) gas is compressed at steady state from 0.8 bar and 17 °C to 3.5 bar with a compressor drawing 10 kW of power. The CO2 flows through the compressor at a rate of 0.1 m3/s through an inlet orifice that is 200 cm2. The gas leaves the compressor at a velocity of 12 m/s. Heat loss from the compressor to the surroundings is roughly 2% of the power fed to the compressor. In addition to the Give,...

The Noyes-Whitney equation is often used to predict the rate at which a solid substance dissolves into water. One form of this equation is: dC/Dt = k(CS-C) where k=DA/Vh . Here D is the diffusivity of the dissolving substance in the electrolyte, A is the area of the sample dissolving, h is the thickness of the diffusion boundary layer, V is the volume of electrolyte, C is the time-dependent concentration of the substance in the electrolyte and Cs is the...

2 Equipartition The laws of statistical mechanics lead to a surprising, simple, and useful result — the Equipartition Theorem. In thermal equilibrium, the average energy of every degree of freedom is the same: hEi = 1 /2 kBT. A degree of freedom is a way in which the system can move or store energy. (In this expression and what follows, h· · ·i means the average of the quantity in brackets.) One consequence of this is the physicists’ form of...
