Find the correct answer within the parentheses 1.The (faster, slower) particles move, the more kinetic energy they have.

2.Particles in the (solid, gaseous) state have the most kinetic energy.

3.Temperature is the measure of the average kinetic (substance, energy) of all particles in an object.

4. When the temperature of a substance (increases, decreases), particles move slower.

5.Potential energy (increases, decreases) as particles get farther apart.

6.Thermal energy is the (product, sum) of potential and kinetic energy.

7.When thermal energy is added to a liquid, kinetic energy (increases, decreases).

8.As a liquid changes to a (gas, solid), the particles move farther apart

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
