For a fixed amount of an ideal gas, an increase in the average speed of the gas molecules could cause which of the following quantities to increase? a. temperature onlyb. volume onlyc. pressure onlyd. volume and pressure onlye. temperature, volume and pressure

Pressure and temperature.

Explanation:

With increase in the average speed of the gas molecules could cause an increase in Temperature and pressure both.

we know that

velocity of the gas v ∝√T in Kelvin clearly, increasing the speed will lead to an increase in temperature of the gas.

Also, with increase in pressure the collision of the gas molecules on the wall's of the container will also increase indicating at increase in pressure as well.

the one with the highest speed

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
