Question

The expression PV= constant is an:
a) isothermal relation
b) adiabatic relation
c) isochoric relation
D) ideal gas expression

Answer 1

These are the Gas laws

PV = Constant  is   an  ISOTHERMAL equation.

$P\ V^\gamma = Constant \ \ is\ an\ Adiabatic\ equation$

P V =  n  R T    is the ideal gas equation.

P / T  = constant  at constant volume,    is an ISOCHORIC equation

V  / T    = constant   is an isobaric equation

Answer 2

(a) PV = Constant         ....................... isothermal relation
(b)P\ V^\gamma = Constant .............................Adiabatic relation                                        
 (c)P V =  n  R T    ................................... ideal gas equation.                                                 
 (d)P / T  = constant  at constant volume.........................  ISOCHORIC equation
  by ideal gas equation PV=nRT
