The process on an ideal gas, shown in figure, is
विकल्प
isothermal
isobaric
isochoric
none of these

उत्तर
isochoric
According to the graph, P is directly proportional to T.
Applying the equation of state, we get
PV = nRT
\[\Rightarrow P = \frac{nR}{V}T\]
\[\text { Given : } P \alpha T\]
\[\text { This means }\frac{nR}{V} \text { is a constant . So, V is also a constant }.\]
Constant V implies the process is isochoric.
