Water is initially contained in a piston−$-$cylinder assembly at p1=100$1=100$ kPa, v1=0.1$1=0\mathrm{.}1$ m3/$3/$kg,$,$ V1=0.2$1=0\mathrm{.}2$ m3.$3.$ Now, the system temperature increases up to T2=160$2=160$degree straight C.$.$ The pressure inside the

cylinder remains constant. Kinetic and potential energy change can be ignored.

What is the initial temperature, T1,$1,$ in degree straight C?$?$
