A freezer case holds tissue samples in a laboratory. The manufacturer claims that under steady state operation the refrigerator has a coefficient of performance of 6.5. The freezer rejects 4.5 BTU/hr by heat transfer to the lab, which is kept at 75 °F. What power input is required in BTU/hr?

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
