You have previously used radiation therapy to induce cell apoptosis in a mouse tumor model in which FGF is over-expressed. Recently, you notice that this therapy is no longer effective and the tumor continued to grow rapidly. Genomic sequencing revealed that those tumor cells have acquired a new loss-of-function mutation in the tumor-suppressor gene Pten, whose protein product normally acts as a phosphatase to dephosphorylate PIP3 into PIP2. Based on this information, you have an idea of why the tumor...

A piston-cylinder device initially contains 75 g of saturated water vapor at 310 kPa . A resistance heater is operated within the cylinder with a current of 0.4 A from a 200 Vsource until the volume doubles. At the same time a heat loss of 2 kJ occurs. a.Determine the final temperature (T2). b. Determine the duration of the process. c. What-if scenario: What is the final temperature if the piston-cylinder device initially contains saturated liquid water?
