This exam asesses course standards 11–15. If you can do the tasks described below, you will satisfy the standards on the quiz.
Calculate the entropy change of an object gaining or losing heat at a constant temperature.
Calculate the entropy change of an ideal gas undergoing a free expansion.
Calculate the entropy change of an object changing temperature as a result of a heat transfer.
Calculate the entropy of a state from its multiplicity.
Identify and explain the formulas for the performance metrics of heat engines, refrigerators, and heat pumps.
Produce, identify, and explain the formulas relating the heat transferred between the device and the hot reservoir, the heat transferred between the device and the cold reservoir, and the work done on or by the device.
For a heat engine, refrigerator, or heat pump, given two, find the other two: heat transferred between the device and the hot reservoir, the heat transferred between the device and the cold reservoir, and the work done on or by the device, and performance.
Cite the thermodynamic criteria for operation of a heat engine, refrigerator, or heat pump in terms of heat transferred between the device and the hot and cold reservoirs and the temperatures of the hot and cold reservoirs.
For a heat engine, refrigerator, or heat pump, produce the formula for maximal performance in terms of the temperatures of the hot and cold reservoirs.
Given the locations and charges of any number of source charges, and the location of a field point, find the electric field at the field point.
Given an electric field at a field point and the charge of a charge at he field point, find the force that the field exerts on the charge.
Given the signs and positions of two electric charges, find the direction of their electrical interaction.
Express Coulomb;s law in terms of Coulomb's constant and also in terms of the permittivity of free space.
I haven’t taught electric potential yet, so you don’t have the information to complete this standard. It will need to wait for next time.
Use Gauss's law to find the electric field formula and general shape of the electric field for highly symmetrical charge distributions:
Use Gauss's law to show that an unbalanced charge on a conductor is on the outside of the conductor.
Given two, find the third: charge, length, linear charge density.
Given two, find the third: charge, area, surface charge density.
Given two, find the third: charge, volume, volume charge density.
