Answer:

All the gas molecules have the same average kinetic energy at a given temperature, under ideal gas assumption.

Explanation:

The three molecules, HBr, NO₂, and C₂H₆, such as any other gas molecule, under gas ideal assumption, have the same average kinetic energy at a given temperature.

The temperature is a measure of the kinetic energy of the of the particles (atoms or molecules) of a gas matter.

At a given temperature, all the gases have the same average kinetic energy of all gases.

That does not mean that all the particles have the same kinetic energy. This principle is not valid for individual particles. Different particles of a same (or differfen)t gas will have different speeds and consequently their individual kinetic energy will vary.

This principle is derived from the molecular kinetic theory and the mathematical expression for the kinetic energy in terms of temperature is:

$KE_{avg}=\frac{3}{2}K_BT$

Where:

KE (avg) = average kinetic energy

KB = Boltzman constant
T = absolute temperature

The acceleration of the ball was 0.6 m·s⁻².

F = ma

a = F/m = 5 N/9 kg × (1 kg·m·s⁻²/1 N) = 0.6 m·s⁻²

Why does the melting of the polar ice caps facilitate the absorption of CO2 by ocean waters?

Korvikt [17]

hi brainly user! ૮₍ ˃ ⤙ ˂ ₎ა

⊱┈────────────────────────⊰

Answer:

The melting of the caps increases the concentration of CO2 in the water, making its absorption faster.

⊱┈────────────────────────⊰

Explanation:

<h2>CO2 absorption </h2>

The polar caps of our planet have in their composition several elements, among them the CO2 that is absorbed by the atmosphere. Cold waters, which are present in the Arctic, have an easier time absorbing CO2 compared to other waters.

When glaciers melt, the CO2 that is present in the mixture is dissolved in the ocean, increasing its concentration. The cold waters that came from the ice caps increase the absorption of CO2.
