Respecting boundaries in each of the following interactions indicate whether the system does (posi- tive) work, has (positive) work done on it or neither and whether the system boundary is effectively diathermal or adiabatic. "effectively", here means your answers should reflect whether a significant amount of heat actually does flow during the given time. provide brief (one word to one sentence) justifications. 1.a the system is the air contained within both a bicycle tire and the pump connected to it. the pump plunger is pushed down, forcing air into the tire. this interaction is over before the air significantly cools. 1.b the system is the water and water vapor within a metal pot covered by a tight-fitting lid. the pot is placed over a flame. the temperature and pressure of the water and water vapor increase. 1.c following the interaction in part b the lid flies off the pot. assume this happens very quickly, too quickly for temperature to change much 1.d the system is the air contained within a room. the room doors and windows are closed and of ordinary construction. a fan within the room is left running for one hour 1.e the system is a mixture of hydrogen and oxygen contained within a rigid metal container. the mixture combusts quickly and then remains in the container

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.
