Question

Match the graphs between the following variables with their names.

$\begin{array}{ccc}& Graphs& Names\\ A.& pressurevstemperaturegraphat& 1.Isotherms\\ & constantmolarvolume& \\ B.& Pressurevsvolumegraphat& 2.Constanttemperaturecurve\\ & constanttemperature& \\ C.& Volumevstemperaturegraphat& 3.Isochores\\ & constantpressure& \\ & & 4.Isobars\end{array}$

Answer 1

$A.\to \left(3\right)B.\to \left(1\right)C.\to \left(4\right)$

A. When the molar volume is constant, the P-T graph is called isochore.

B. When the temperature is constant, the P-V graph is called isotherm.

C. When pressure is constant, the V-T graph is called isobar.
