Imagine you fill an insulated cup almost full with chopped or crushed ice, and measure the temperature after a minute or two, once it’s all come to thermal equilibrium. Since this ice is frozen water, the temperature should be at 0°C or not more than a couple of degrees below. Then, imagine you add a bunch of salt and stir it around.
What do you think the lowest temperature you can attain will be? Why? What happens to the amount of liquid present if you keep stirring and adding salt? How can we understand this phenomenon in terms of thermal and bond energy systems?
Develop an explanation for the changes you would observe in this physical system (decrease in temperature and change of phase) in terms of the Energy-Interaction Model. Preview the document

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.
