The natural tendency is for entropy to over time.

a) decrease
b) increase
c) remain constant
d) constantly fluctuate

quiz!

answer: option (b) is the correct answer.

explanation:

entropy is defined as the degree of randomness. this means that in an isolated system the particles will be in disorder.

it is an extensive property and depends on the mass of system. it does not depend on the path through which the process has taken place.

entropy increases because heat supplied to the substance or heat absorbed by the particles from the surrounding irrespective of temperature change.

thus, we can conclude that the natural tendency is for entropy to increase over time.

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
