A system consisting of 0.0387 moles of a diatomic ideal gas is taken from state A to state C along the path in the figure below. Point A (2 L, 3 atm) --> point B (2 L, 8 atm) --> point C (8 L, 6 atm). (A) How much work is done on the gas during this process?
(B) What is the lowest temperature of the gas during this process?
(C) Find the change in internal energy of the gas in going from A to C. Hint: Adapt the equation (for the change in internal energy of a monatomic ideal gas)
(D) (d) Find the energy delivered to the gas in going from A to C.

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
