Q1. Suppose that 0.10mol of argon gas is admitted to an evacuated 50cm3 container at 20° C. The gas then undergoes isobaric heating to the temperature of 300°C. What is the final pressure of gas? What is the final volume?

Q2. Two coils of wire are aligned with their axes along the z-axis. Coil 1 is connected to a power supply and conventional current flows clockwise through coil 1, as seen from the location of coil 2. Coil 2 is connected to a voltmeter. The distance between the center of the coils is 0.16m.

Coil 1 has N1 = 550 turns of wire, and its radius is R1 = 0.07m. The current through coil 1 is changing with time. At t=0 s, the current through coil 1 is I0 = 17A. At t=0.4 s, the current through coil 1 is I0.4 = 6A.

Coil 2 has N2 = 260 turns of wire, and its radius is R2 = 0.04m.

At time t=0, what is the magnetic flux through one turn of coil 2? Consider that all turns of coil 1 contribute to the magnetic field. Note also that the coils are not very far apart (compared to their radii), so you can't use an estimated formula here.

At t=0.4 s, what is the magnetic flux through one turn of coil 2?
