a=1.3661 and b=1.3483 according to table 2.3
6. (50 pts. Now that you have worked problem 9.46, you should have an understanding of the following problem, which is rather involved but is extremely instructive for understanding phase transitions in particular and equilibrium in general. a. Find the temperature at which N, boils at a pressure of 1 bar assuming N2 is well described by a van der Waals equation. Use the van der Waals constants given in Table 2(16).3. Compare...

Compare these calculated values to the experimentally determined values, a 1.39 x 106 cm atm/mole and b-39.1 cm/mole. Such poor agreement is quite typical, simply indi- cating the inadequacy of the van der Waals equation. 14-2 THE VAN DER WAALS EQUATION We start with Eq. (14-3), and take...

2. (a) Two small metallic spheres, each of mass 2.00 g, are suspended as pendulums by light, non-conducting strings as shown below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of 30° with respect to the vertical. (a) If the strings are each 10.0 cm long, what is the magnitude of the charge on each sphere? Assume that the gravitational force between the two...

You are given a kinematics problem in two dimensions where the object is in free-fall, and it hits the ground. Which of the following is a logical choice to make when solving the problem? Set the final y-velocity (just before it hits the ground) to zero. Set the initial x-velocity to zero. Set the final y-position to zero. Set the initial y-velocity to zero. Set the final x-position to zero.

A device for accurately generating small forces between two wires can be created by the rectangular circuits shown in the figure on the worksheet for this problem. In the left circuit, the battery has an emf of ε1 = 7 V and a resistor with fixed resistance R1 = 6 ohms. In the right circuit, the battery has emf of ε2 = 7 V and a variable resistor with resistance R2 ohms. The circuits are L = 12 cm wide...

Problem 2: I told you it would show up again! (8 pts) Consider two different 500 ml vessels, each crammed with 1 mole of gas at 500 K. In one vessel, the gas is water, H20. In the other vessel is ethane, C2H6. Notably, these two gases are special: the van der Waal's parameter value for a is roughly the same as each: a = 5.54 L2 bar/ mol? (water), 0 = 5.56 L bar/mol (ethane). Because a is the...
