T he conditions at sea level are 14.7 psia and 59°F and temperature at 10,000 ft according to a) Isothermal atmosphere (5 Points) 15°C. Calculate the pressure
What is the expression for pressure as a function of density P(density) of an isothermal atmosphere (ideal gas at temperature T=T0)
1. For the earth, an estimate of the variation of pressure with altitude above the surface of the earth is made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. A significant error in this estimate arises from the assumption that the temperature of the atmosphere, T, is isothermal instead of decreasing with altitude. This decrease with altitude y in...
Suppose the atmosphere has its pressure given by p ( z ) = p 0 e ^ − z / H with p 0 = 1 atm and T ( z = 0 ) = 273 K. Now suppose a 1 kg parcel is lifted adiabatically one scale height H . How much work does the parcel do on the environment in the process? What is the change in its specific internal energy, u ?

problem 40 with parts 40. The atmospheric pressure (force per unit area) on a surface at an altitude z is due to the weight of the column of air situated above the surface. Therefore, the difference in air pressure p between the top and bottom of a cylindrical volume element of height Az and cross-section area A equals the weight of the air enclosed (density ρ times volume V-: ΑΔε times gravity g), per unit area: Let Δ、→0 to derive...
31 and 33 Draw a diagram for each of processes (isothermal, isobaric, isochoric) in variables (P, V), (P, T) and (V, T). Express density of an ideal gas using the equation of state: PV = n/M RT. Explain every step. One mode of oxygen gas is at a pressure of 6.00 and a temperature of 27.0 degree C. If the gas is heated at constant volume until the pressure triples, what is the final temperature? If the gas is heated...
71 Determine the slope (in atm/K) of a solid- liquid coexistence line (in a P-T phase diagram) at 273.15 K, given that AHfus = 6.01 kJ /mol, Vi 0.0180 L/mol, and Vs 0.0196 L/mol. Make sure your slope has appropriate units for the type of phase diagram we are dealing with (i.e. it should only have pressure and temperature units).
Over narrow ranges of temperature (T) and pressure (P), the volume of a fluid may be expressed as V = C exp(?PT) exp(-?TP), where ?P denotes the isobaric thermal expansion coefficient of the fluid, ?T denotes the isothermal compressibility of the fluid, and C denotes a constant (independent of both P and T). Show that V, as expressed above, is a state function. Edit: It appears as though it's V = C^((?PT)(-?TP)).
