For process 0 to 7, which of the following is a constant? p is pressure, V is volume, and T is the temperature. Select all apply.p V/T p/T T pV V The image is a graph depicting pressure (p) versus volume (V) with isotherms labeled \(T_1\), \(T_2\), and \(T_3\). The isotherms represent constant temperature lines, with \(T_1 < T_2 < T_3\), and they are illustrated as dotted red curves sloping downwards from left to right, indicating that pressure decreases as volume increases for a fixed temperature.Key Features of the Graph:- The vertical axis represents pressure (p), while the horizontal axis represents volume (V).- Several arrows originate from a central point marked 0, extending to points 1 through 8, indicating various state changes or processes.- Points 6, 5, and 4 are shown along the isotherms in the direction of increasing volume and decreasing pressure.- The lines connecting these points mimic typical thermodynamic paths, where the arrows suggest transitions between states under different conditions.- The illustration includes three isotherms, with \(T_3\) being the highest temperature and \(T_1\) the lowest. This graph can be used to discuss thermodynamic concepts such as pressure-volume relationships, isothermal processes, and the behavior of gases under varying conditions.

With the help of the figure, we need to answer the question.Here we are dealing with the particular situation, where the state change from 0 to 7. Notice in the curve it is mentioned that it is an isotherm. Isothermal means the temperature remains constant. Hence, the temperature is constant. Now when the temperature is constant then we can apply Boyle's theorem i.e. pV=constant. Hence, here two quantities remains constant T and pV.
