Question

Match the graphs between the following variables with their names:

$\begin{array}{cccc}& \text{Graphs}& & \text{Names}\\ \text{(A)}& \text{Pressure vs temperature graph at constant molar volume.}& \text{i)}& \text{Isotherms}\\ \text{(B)}& \text{Pressure vs volume graph at constant temperature.}& \text{ii)}& \text{Constant temperature curve}\\ \text{(C)}& \text{Volume vs temperature graph at constant pressure.}& \text{iii)}& \text{Isochores}\\ & & \text{iv)}& \text{Isobars}\end{array}$

Answer 1

The correct match can be represented as:

$\begin{array}{cccc}& \text{Graphs}& & \text{Names}\\ \text{(A)}& \text{Pressure vs temperature graph at constant molar volume.}& \text{iii)}& \text{Isochores}\\ \text{(B)}& \text{Pressure vs volume graph at constant temperature.}& \text{i)}& \text{Isotherms}\\ \text{(C)}& \text{Volume vs temperature graph at constant pressure.}& \text{iv)}& \text{Isobars}\end{array}$

$\left(A\right)\to \left(iii\right)$,
Pressure vs temperature graph at constant molar volume are known as Isochores.

$\left(B\right)\to \left(i\right)$,
Pressure vs volume graphs at constant temperature are known as Isotherms.

$\left(C\right)\to \left(iv\right)$,
Volume vs temperature graphs at constant pressure are known as the isobars.
