Question

Graphs between pressure and volume are plotted at different temperatures. Which of the following isotherms represents Boyle’s law as $PV $= constant?
$\left(T_{1} >T_{2} >T_{3}\right)$

• A. Only (ii) is correct representation of Boyle’s law.
• B. Only (iv) is correct representation of Boyle’s law.
• C. All are correct representations of Boyle’s law.
• D. None of these representations is correct for Boyle’s law.

Answer 1

Answer: (C)

Byles Law :
It states that pressure of a given mass of an ideal gas is inversely proportional at a constant temperature.
$PV = nRT \longrightarrow $ constant
$PV = K$
$P = K \left(\frac{1}{ V }\right)$
$PV =\frac{K}{P}(P)$
$\log P =-\log V +\log K$
