True or false? The molar mass of a gas determines the amount of kinetic energy of the gas.
HACTEHA [7]
The answer is false..............<span>kinetic theory of gases is a topic that can explain many everyday observations. Have you ever wondered why water boils faster at higher altitudes? Or why inflatable pool toys seem flat after sitting in a cold garage? How about why you can smell a candle all throughout the house? All of these phenomena and many more can be explained by the kinetic theory of gases.</span>

How much energy is required to vaporize 14.27 grams of water at its<br> boiling point? *
laila [671]

Energy required to vaporize : 32.3 kJ

<h3>Further explanation </h3>

The heat to change the phase can be formulated :

Q = mLf (melting/freezing)

Q = mLv (vaporization/condensation)

Lf=latent heat of fusion

Lv=latent heat of vaporization

Mass of water = 14.27 g

Latent heat of vaporization ( boiling point of 100 ºC) :  2260 J/g

Energy required :

\tt Q=m.Lv\\\\Q=14.27\times 2260\\\\Q=32250.2~J\approx 32.3~kJ

When two protons and two neutrons combine to form 4He, it is found that this helium nucleus is less massive than the sum of the
Fynjy0 [20]

Answer:

Explanation:

This signifies a defect in mass. The phenomenon is known as mass defect. Mass defect is compares the mass of an isotope to that of the nucleons in the nucleus.

The mass defect implies the energy that was given off when the protons and neutrons combine to form the new helium atom. The mass defect helps us to understand why the mass of an atom might not eventually correspond to what we obtain theoretically by calculation.
