One process for decaffeinating coffee uses carbon dioxide ( M = 44.0 g/mol) at a molar density of about 14,0 mol/m 3 and a temperature of about 60 ℃. (a) Is CO 2 a solid, liquid, gas , or supercritical fluid under those conditions? (b) The van der Waals constants for carbon dioxide are a = 0.3658 Pa ⅇm 6 /mol 2 and b = 4.286 × 10 − 5 m 3 /mol. Using the van der Waals equation, estimate pressure of CO 2 at that temperature and density. `

Study of body parts and their functions. In this combined field of study, anatomy refers to studying the body structure of organisms, whereas physiology refers to their function.
An ideal gas in a 1.25-gallon[gal] container is at a temperature of 135 degrees Celsius [°C] and pressure of 2.4 atmospheres [atm]. If the gas is oxygen (formula: O2, molecular weight=32 grams per mole [g/mol]), what is the amount of gas in the container in units of grams [g]?
The ideal gas law relates the pressure P, volume V, and temperature T of an
ideal gas:
PV = nRT
where n is the number of moles and R = 8.3145 J/(K mol). Plots of pressure
versus volume at constant temperature are called isotherms. Plot the isotherms
for one mole of an ideal gas for volume ranging from 1 to 10 m', at tempera-
tures of T = 100, 200, 300, and 400 K (four curves in one plot). Label the
axes and display a legend. The units for pressure are Pa. n=1
An amount of gas has volume 250.0L at 17°C and 3.0 atmospheric (atm) pressure. If the
temperature and pressure are to be reduced to STP, what should be the corresponding volume?
[STP stands for standard temperature and pressure indicating 0°C and 1 atm, and V varies directly
with absolute T]
