This experiment deals with the relationship between volume and temperature for a fixed amount of gas at constant pressure. design an experiment, which would allow you to study the relationship between pressure and temperature for a fixed amount of gas at constant volume. show a diagram of the apparatus and a plot of p versus t for the data you expect to obtain. is the relationship between p and t direct or inverse?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
