|A/c to Boyle's law P is inversely proportional to V when temp remains constant.|
|Manoj said: (Aug 29, 2014)|
|Yes @Vishal pv=c at const. temperature A/c to Boyle's law.|
|Indra said: (Oct 18, 2014)|
|Yes pv=c at constant temp.|
|Bharat said: (Mar 4, 2015)|
|Why is this false in isothermal process pv is constant right?|
|Alb said: (Mar 31, 2015)|
|Process is given as heated that means there will be change in temperature. So it must be hyperbolic process.|
|Vishal said: (Jul 30, 2015)|
|Hyperbolic process is also called isothermal process.|
|Anil said: (Nov 25, 2015)|
|Hyperbolic process is called isochoric process.|
|Vishal Joshi said: (Jul 9, 2016)|
|It is the isothermal process.
And isothermal process is hyperbolic one.
|Sathaiah Chitikesi said: (Aug 10, 2016)|
|In the gas law, PV = mRT, for a given gas m and are constant. The product of P and V is constant when T is constant. Thus isothermal process (for gas only) is the correct answer.
It is not known why the answer was given is B (ie. NO).

|In gas PV = constant. It is an isothermal process and in steam, PV = constant in the wet region is a hyperbolic process and superheated state is the isothermal process. Therefore right answer is "A".|

|It may be noted that the hyperbolic process is governed by Boyle, s law i.e. p we = constant. If we plot a graph of pressure and volume, during the process as shown in fig we shall get a rectangular hyperbola. Hence, this process is termed as a hyperbolic process. It is merely a theoretical case and has a little importance from the subject point of view. Its practical application is an isothermal process.|
|M.T.Naidu said: (Dec 24, 2016)|
|In an isothermal process, the product of pressure and volume is constant, hence correct option is yes.|
|Rathod said: (Jan 5, 2017)|
|According to me, Correct answer must be yes.|
|Sateesh said: (Jun 10, 2017)|
|The correct answer is A, Yes.|
|S Bera said: (Jun 28, 2017)|
|Correct answer is A.|

|1. Hyperbolic Process- it is the process where the gas is heated or expanded in such a way that the product of its pressure and volume remains constant. This process is governed by Boyle's law.
Mathematically, p * v = constant
2. Isothermal Process- it is the process in which the temperature of the working substance remains constant during expansion or compression. In an isothermal process, there is no change in temperature and internal energy.
|Niranjan Das said: (May 9, 2018)|
|I think the isothermal process is the right answer. But If hyperbolic process are available then then we choose hyprobalic process right.|
|Mistri said: (Aug 1, 2018)|
|Heating does not signify the increase in temp.|
|Comiefa said: (May 24, 2020)|
|Its only correct for ideal gases not for all gases|
