Refrigerant-134a enters the coils of the evaporator of a refrigeration system as a saturated liquid–vapor mixture at a pressure of 160 kPa. The refrigerant absorbs 180 kJ of heat from the cooled space, which is maintained at -5°C, and leaves as saturated vapor at the same pressure. Determine (a) the entropy change of the refrigerant, (b) the entropy change of the cooled space, and (c) the total entropy change for this process

1.Starting with this provided code, add the following functionality: Replace hardcoded strings “Zero”, “One”, “Two”, “Three” in the ArrayList based on user typed input (use Scanner or JOptionPane classes). The user will be prompted for the String to be stored in the ArrayList and then hit enter. The user will be able to continue to add items to the ArrayList until they just hit enter without typing anything. Once the user does this (hits enter without typing anything), the program will display all of the elements of the ArrayList, both the index and String values, in a table. It will do this via a single loop making use of an iterator method. 2. Starting with this provided code, add the following functionality: Use a Try/Catch block so that the exception is caught and the program exits a bit more gracefully. Save this file as TryCatch.java. (Be sure to rename the Public Class accordingly.) Starting with the provided code again (without the Try/Catch block), fix the code so that ...

independent variable

By
Which of the listed variables does a researcher mainly use in his or her approach with intent to establish validity - specifically, construct validity? ·         independent variable ·         confounding variable ·         dependent variable ·         participant variable ·         extraneous variable ·         third variable Instructions: With our engagement in this discussion we will likely touch upon learning objectives/competencies 2.2 and 2.4 as dependent upon the various variable selections and replies. (a) Please briefly define the two concepts (variable type(s) selected from the list and construct validity) using our text by Cozby and Bates (2015) or another credible source. (b) Then, support your view...
