If a graph is plotted between log V and log T for 2 moles of a gas of constant pressure of 0.0821 atm, then which of the following statements are correct?

Answer»

<P>The curve is straight LINE with slope -1.
The curve is straight line with slope +1
The INTERCEPT on y-axis is equal to 2.
The intercept on y-axis is equal to 0.3010.

Solution :`PV=nRT`
`log V =logT+"log"(nR)/P`
slope =1
intercept `="log"(nR)/P=log[(2xx0.0821)/0.0821]=0.3010`
