Document Summary

Chapter 13 notes (lec 2) y geomorphology is the process-based study of landforms and dynamic equilibrium. y denudation is any process that wears away or rearranges landforms. This builds mountains and weathers to shape landmasses y equilibrium: sun converts radiation into heat energy. Hydrologic cycle imparts kinetic energy through mechanical motion. Chemical energy made available from atmospheric reactions within the crust y dynamic equilibrium model: emphasized a balance among force, form and processes. Building mountains, weathering and shaping land masses. y the rock cycle makes up the formations of landmasses and natural disasters. When rocks hit and get folded, this causes mountains while the hitting can also cause earthquakes and volcanoes. y weathering. Is influenced by the character of the bedrock: some are hard/soft, soluble/insoluble, and broken/unbroken. It is a process that attacks rocks and breaks it down into smaller pieces of rocks called regolith: weathering is broken down into two proal growth and unloading. cesses, physical and chemical.

Air conditioners operate on the same principle as refrigerators. Consider an air conditioner that has 7.00 of refrigerant flowing through its circuit each cycle. The refrigerant enters the evaporator coils in phase equilibrium, with54.0 of its mass as liquid and the rest as vapor. It flows through the evaporator at a constant pressure and when it reaches the compressor 95 of its mass is vapor. In each cycle, how much heat is absorbed by the refrigerant while it is in the evaporator? The heat of vaporization of the refrigerant is 1.50×105 .Express your answer numerically in joules. =5.15×105 Correct Part BIn each cycle, the change in internal energy of the refrigerant when it leaves the compresser is 1.20×105 . What is the work done by the motor of the compressor?Express your answer in joules. =1.20×105 Correct Part CIf the direction of the refrigerant flow is inverted in an air conditioner, the air conditioning unit turns into a heat pump and it can be used for heating rather than cooling. In this case, the coils where the refrigerant would condense in the air conditioner become the evaporator coils when the unit is operated as a heat pump, and, vice versa, the evaporator coils of the air conditioner become the condenser coils in the heat pump. Suppose you operate the air conditioner described in Parts A and B as a heat pump to heat your bedroom. In each cycle, what is the amount of heat released into the room? You may assume that the energy changes and work done during the expansion process are negligible compared to those for other processes during the cycle.Express your answer numerically in joules. =
