<u>Answer:</u>
The correct answer option is C. Kinetic energy from vibration.
<u>Explanation:</u>
The energy of the random motion of the particles of an object is referred to as the internal energy of that object (substance). So the type of energy that makes up most of the internal energy of a solid substance is kinetic energy from vibration.
Internal energy is related to the temperature. When heat is supplied to an object, the molecules vibrate and energy of these molecules increases.

Answer:
N₂= 697.24 m/s,
O₂= 652.38 m/s
CO₂= 393.35 m/s
Explanation:
The rms speed, of a gas is the following:
<em>where R: is the ideal gas constant, T: is the temperature and M: is the molar mass. </em>
<u>Knowing that the molar mass of the given gases are:</u>
N₂ = 14.0067 g/mol = 14.0067x10⁻³ kg/mol
O₂ = 15.999 g/mol = 15.999x10⁻³ kg/mol
CO₂ = 44.009 g/mol = 44.009x10⁻³ kg/mol
Also that T is 0 °C = 273 K, and R = 8.314 J/ K.mol = 8.314 kg.m². s⁻². K⁻¹. mol⁻¹. The rms speed of the gases are:
For N₂:
For O₂:
For CO₂:
Therefore, the rms speed of N₂ is 697.24 m/s, of O₂ is 652.38 m/s and of CO₂ is 393.35 m/s

<span> Mass is a quantified value of how much matter is in you, while weight takes into account the effect of gravity. People will "weigh" less on the moon because of the lesser gravity, but they still have the same mass.</span>
The rate at which an object moves is called speed or velocity depending if the direction does or doesnt matter
