Suppose that a perfectly insulating box has two chambers inside of it, each with a volume of 0.35 L. The chambers are connected by a stopcock valve. When the valve is closed, no gas passes between the chambers. Initially, when the valve is closed, the chamber on the left is filled with gas at a temperature of 325 K and a pressure of 0.90 atm. The chamber on the right is evacuated so that it contains no gas.

When the stopcock valve is opened, the gas redistributes to fill both chambers, eventually reaching a new equilibrium state.

Determine the change in internal energy Δ between the final and the initial states of the gas.

jupiter

explanation:

it is so massive and has such a strong gravitational pull its likely prevented the formation of a planet between itself and mars in the asteroid belt

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
