Consider two processes for taking a 0.200-mol sample of helium gas (monatomic he) from an initial state i to a final state f. given that the gas behaves ideally, in both processes, the initial temperature and pressure ar undergoes an isothermal compression to a volume of 2.00 x 10-3 m3 and pressure ps in process b, the gas undergoes an adiabatic compression followed by an isobaric compression to vf = 2.00 x 10-3 m3 a. draw the pv diagram showing both processes. 150 k, the gas pressure is 1.01 x 105 pa. in process a, the sample e b. find the magnitude of the difference in the quantities of energy transferred thermally to the gas qb-ql in the two processes.

Suppose that an electromagnetic wave which is linearly polarized along the x−axis is propagating in vacuum along the z−axis. the wave is incident on a conductor which is placed at z > 0 region of the space. the conductor has conductivity σ, magnetic permeability µ and electric permittivity ε. (a) find the characteristic time for the free charge density which dissipates at the conductor. (b) write the maxwell equations and derive the wave equation for a plane wave propagating in a conductor. (c) find the attenuation distance at which the incident amplitude reduces to e ^−1 of its initial value. (d) find the electric and magnetic fields inside the conductor. 8 (e) find the power loss per area of the incident electromagnetic wave at the surface of conductor.
