PHYS 2 Chapter Notes - Chapter 18.1 - 18.4: Van Der Waals Equation, Molar Mass, Ideal Gas
Document Summary
State variables = quantities that describe the conditions/state in which a particular material exists. Volume v is proportional to the number of moles n. Volume varies inversely with the absolute pressure p. The pressure is proportional to the absolute temperature t. Equation of state = an equation expressed when the relation among is simple. Molar mass = molecular weight = mass per mole. Is the number of moles of substance. Are constants that are different for different gases is the volume of a mole of molecules. Van der waals equation = includes the volumes of the molecules themselves and the attractive forces between them pv-diagram = a diagram in which pressure is a function for volume at a particular constant temperature. Isotherm = the curve of a pv-diagram that represents behavior at a specific temperature. For an ideal gas, constant mass (constant number of moles): Molecule = what makes up a specific compound.
