As an astronomer, you are in charge of an ancient collectionof highly-valuable iron-type meteorites. The collection waspassed down through generations, originally belonging to agroup of people who measured volume in extinct units ofdracks and magonites. You intend to sacrifice the smallest ofthe meteorites for scientific analysis. What is the volume ofthe smallest meteorite in your collection in units of dm??(1 drack = 2.2 L exactly) (1 magonite ~ 0.5289 L)(1 m = 100 cm) (1 m = 10 dm)
(a) The ideal gas equation of state is a fairly simple expression of the relationship between the physical properties of a gas. In Module 4, we will consider some other equations of states, one of which is the van der Waals equation of state, (? + a n2/ v2) (V-nb)=nRT where a and b are constant coefficients for a given substance, and P, V, T, and n have their usual meaning. Find the partial derivative (P/T)v for this equation of state . b) Mathematically, it is known that for three variables that are related to one another (as P, Vm, and Tare here) by a function (or equation of state), one can show (??/??)z (??/??)x (??/??)y =−1 (note the cyclic variation of the three variables).Using this relationship, and the definitions of kT(coefficient of isothermal compressibility) and a (coefficient of isobaric thermal expansibility), find a simple equation relating the van der Waals parameter, b, to Vm, a, and kT. (For a discussion of this sort of…
