Question

Which of the following relationship when graphed give a rectangular parabola for helium gas? I. KE vs T at constant P and V II. V vs (1/T) at constant P and n III. P vs V at constant T and n (A) III (B) I and III (C) II (D) II and III

Tardigrade Admin · Accepted Answer

Graph of P vs V at constant T is a rectangular parabola.

Graph of V vs

\frac{1}{T}

at constant P and n is a rectangular parabola.

Kinetic energy

\propto T

Hence a graph between KE v/s T will be in straight line.

Q. Which of the following relationship when graphed give a rectangular parabola for helium gas? I. KE vs T at constant P and V II. V vs T1​ at constant P and n III. P vs V at constant T and n

III

I and III

II

II and III

Graph of P vs V at constant T is a rectangular parabola. Graph of V vs T1​ at constant P and n is a rectangular parabola. Kinetic energy ∝T Hence a graph between KE v/s T will be in straight line.

Q. Which of the following relationship when graphed give a rectangular parabola for helium gas?

I. KE vs T at constant P and V

II. V vs $\frac{1}{T}$ at constant P and n

III. P vs V at constant T and n

Graph of P vs V at constant T is a rectangular parabola.

Graph of V vs $\frac{1}{T}$ at constant P and n is a rectangular parabola.

Kinetic energy $\propto T$

Hence a graph between KE v/s T will be in straight line.
