Question

For the given $ pV $ isotherms, which of the following is correct for $ T_{1}, T_{2}, T_{3} $ ?

• A. $ T_{1} < \, T_{2} <\, T_{3} $
• B. $ T_{3} < \, T_{2} <\, T_{1} $
• C. $ T_{2} < \, T_{3} <\, T_{1} $
• D. $ T_{1} < \, T_{3} <\, T_{2} $

Answer 1

Answer: (A)

According to Boyle's law, the product of volume and pressure of a given gas is constant at constant temperature. The curve between pressure and temperature is plotted as

On increasing temperature the curve shifts to higher value
Hence, from the given options (according to the curve) $T_{1}<\,T_{2}<\,T_{3}$
