Question

Which has the maximum internal energy at $290\mathrm{K}$- Neon gas, nitrogen gas, or ozone gas?

Answer 1

Internal energy

• The total of the kinetic energies of the particles in an ideal gas is its internal energy.
• According to the kinetic molecular theory, a gas's temperature is proportional to the average kinetic energy of its particles.

Maximum internal energy at $290\mathrm{K}$

• Ozone has a positive or negative impact on life on Earth depends on its location in the atmosphere.
• It is a geological and fella material that appears in the top atmosphere.
• Gas internal energy$=\frac{fnRT}{2}$.
• Here $f$ denotes the number of degrees of freedom, $n$ is the number of moles, $R$ is a gas constant and $T$ is the temperature.
• A gas's internal energy is propositional to degree of freedom.
• The degree of freedom of a gas is proportional to its atomicity.
• As a result, the internal energy is proportional to the atomicity of a gas at a given temperature.
• The ozone has the highest atomicity, which is three, compared to Neon gas, and nitrogen gas, which have two atomicity.
• Therefore, the internal energy of ozone gas is the highest $290\mathrm{K}$.
