Acalorimeter has a heat capacity of 1265 j/oc. a reaction causes the temperature of the calorimeter to change from 22.34oc to 25.12oc. how many joules of heat were released in

this process?

heat released is

Explanation:

It is given that, heat capacity of calorimeter is, H =

Also , initial temperature of calorimeter,

final temperature of calorimeter,

We know , Heat will release when it is positive.

So, heat released , Heat =.

Since it is positive. Therefore, heat released is

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
