The experiment was using a calorimeter made from a styrafoam cup. we were testing pennies and a steel bolt. we tested the specific heat capacity of water and the metals by boiling water and testing the temperature before and after. answer all parts : )
had you started the experiment with water at a temperature cooler than room temperature, for example refrigerated water, how would this affect your results? explain your reasoning.
2. we ignored the heat absorbed by the calorimeter cup in our calculations. explain why was this permissible.
3. list and explain one specific experimental cause of the difference between the measured specific heat and the accepted value. how could you possibly improve the experiment to reduce this percent difference?
4. is the heat exchange between the metal and the water in the cup primarily through radiation, conduction, or convection? explain your answer.

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
