A58.1g sample of quartz is put into a calorimeter that contains 250.0g of water. the quartz sample starts off at 98.4°c and the temperature of the water starts off at 25.0°c. when the temperature of the water stops changing it's 27.9°c. the pressure remains constant at 1 atm. calculate the specific heat capacity of quartz according to this experiment. be sure your answer is rounded to the correct number of significant digits.

Explanation:

Given:

We have:

Assuming that heat loss is neither from any of the components before mixing nor from the mixture just after mixing. Also the container does not absorbs any heat.

Therefore,

heat gained by the water = heat lost by the quartz

    where: specific heat capacity of quartz

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
