Answer #1

Answer: ------ greater than the change in entropy for the surroundings

Consider an Air Conditioner, where heat flows from system (indoor) to surroundings (outdoor) in which change in entropy for the system is greater than the change in entropy for the surroundings. Outside area is large compared to inside room area. So inside temperature is relatively very low compared to outside as temperature distributed evenly over a large entire space.

Which of the following situations would most likely exist if a firm adheres to a moderate current asset investment policy? Group of answer choices The firm maintains relatively large amounts of current assets. Once equilibrium is attained, the amount of current assets will equal the amount of current liabilities. The firm's level of accounts receivable is greater than its level of accounts payable. The firm holds minimum amounts of cash and marketable securities, inventories, and receivables. The firm maintains a...

It is possible to go from a given initial equilibrium state of a system to a given final equilibrium state by a number of different paths, involving different intermediate states and different amounts of heat and work. Since the internal energy of a system is a state function, its change between any two states must be independent of the path chosen. The heat and work flows are, however, path-dependent quantities and can differ on different paths between given initial and...
