In a crude model of a rotating diatomic molecule of chlorine (Cl2), the two Cl atoms are 2.00 ✕ 10-10 m apart and rotate about t

Troyanec [42]

Answer:

$1.03723\times 10^{-20}\ J$

Explanation:

r = Radius of atom = $1\times 10^{-10}\ m$

m = Mass of chlorine atom = $5.88\times 10^{-26}\ kg$

$\omega$ = Angular speed = $4.2\times 10^{12}\ rad/s$

The moment of inertia of the system is given by

$I=2mr^2\\\Rightarrow I=2\times 5.88\times 10^{-26}\times (10^{-10})^2\\\Rightarrow I=1.176\times 10^{-45}\ kgm^2$

Kinetic energy is given by

$K=\dfrac{1}{2}I\omega^2\\\Rightarrow K=\dfrac{1}{2}\times 1.176\times 10^{-45}\times (4.2\times 10^{12})^2\\\Rightarrow K=1.03723\times 10^{-20}\ J$

The rotational kinetic energy of one molecule of the atom is $1.03723\times 10^{-20}\ J$

According to Charles's law, for a fixed quantity of gas at constant pressure, which of the given quantities is constant? Accordi

Naddik [55]

Charles's <span>law is also known as the law of volumes explained the relation between the volume of gas and its temperature.

Charles's law states that: " At constant pressure, the volume of a certain mass of gas is directly proportional to its temperature in kelvin".
This means that:
V = T*constant
V/T = constant

Based on this, the correct choice is:
</span><span>a) V/T</span>
