Question

State True or False.

The plot of $PV$ vs $P$ at particular temperature is called isobar.

• A. True
• B. False

Answer 1

The correct option is B False

According to ideal gas equation,
$PV=nRT$,
at constant $T$
$PV$ = constant
An isobaric process is a thermodynamic process in which pressure stays constant: $\Delta$P = 0. For an ideal gas, this means the volume of a gas is proportional to its temperature (historically, this is called Charles' law ).
