We know that the work done by any thermodynamic process is, in general, found by the relation: , = − 8 /01 23 24 Using the Ideal Gas Law (PV=nRT), derive relations for the amount of work done in a system during a process in which: 1. P is constant (isobaric process) 2. T is constant (isothermal process)

Arock collection comes from which part of earth?

What is the primary force that suspension bridges use cables to hold their spans up? a. tension force b. resistance force c. normal force d. elastic force e. applied force

Aparticle's position is given by x = 3.00 - 9.00t + 3t2, in which x is in meters and t is in seconds. (a) what is its velocity at t = 1 s? (b) is it moving in the positive or negative direction of x just then? (c) what is its speed just then? (d) is the speed increasing or decreasing just then? (try answering the next two questions without further calculation.) (e) is there ever an instant when the velocity is zero? if so, give the time t; if not, answer "0". (f) is there a time after t = 3 s when the particle is moving in the negative direction of x? if so, give the time t; if not, answer "0".
