The boiling point of mercury at 1 atm is 357 celsius, and the amount of heat necessary to reversibly evaporate a kilogram of mercury already at the boiling point is aq = 72780 kilogram of mercury undergoing a process of evaporation: cal. detrmine for a. a) work done by the mercury vapor against the atmosphere assuming it behaves as an ideal gas
b) the change in internal energy c) the change in entropy d) the change in enthalpy e) the change in helmholtz free energy f) the change in gibbs free energy necessary data: the density of liquid mercury is 13.55 kg/l hint: you can treat the mercury vapor as an ideal gas. note that you don't need to know the equation of state of liquid mercury for this particular problem. you can calculate everything necessary with knowledge from blocks two and three.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

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
