Liquid nitrogen of 10 lbm mass is located inside the container under the 350psi pressure at the saturated liquid stage. It was a hot day and the technician forgot to take the container to the lab. The pressure was gradually increased due to heating the container. At some time, the technician noticed the pressure gage reading is increased to 450 psi and he rushed to hide the container to the lab to cool it down. Draw the process using the phase envelop in T-V scale. Show all stages and denote by arrow the process. Using NIST webbook determine: The initial density of the liquid nitrogen in kg/m3. The volume in m3 of the liquid nitrogen inside the container. The initial temperature in C inside the container. What is the temperature in C at 450psi? Is nitrogen still at the liquid stage? Why do you think so?

can you show were you got value for initial temperature??whats the temperature in celsius at 450 psi? is nitrogen still a liquid stage??why?
