A person is drinking a glass of soda with ice.
prisoha [69]

The relative kinetic energy of molecules in the soda is least energy and above the soda in the glass is greatest energy.

The relative kinetic energy of gas molecules increases with increase in the mean distance between the gas molecules.

Also, relative kinetic energy of gas molecules increases with in the temperature of the gas molecules and decreases with a decrease in the temperature of the of the gas molecules;

ΔK.E ∝ T

The ice in the soda lowers the temperature of the gas molecules, thereby reducing their average speed which in turn reduces the average kinetic energy of the gas molecules in the soda.

Above the soda in the glass, the concentration of the gas molecules is less and their mean distance is greatest when compared to inside the soda. This results to an increase in the speed of the gas molecules which increases their average kinetic energy.

Thus,  the relative kinetic energy of molecules in the soda is least energy and above the soda in the glass is greatest energy.

Red shift data shows that galaxies are O expanding O shrinking O moving away O moving closer
Anon25 [30]

Answer:

Should be moving away

Explanation:

Red is a longer wavelength therefore further away. Wavelength is stretched out more and on the red end. I hope this is right. I decided to research and answer since you didn’t have other answers. Are you taking this on edg? I hope I helped!

Who said Freedom is the oxygen of the soul?
____ [38]

Moshe Dayan said that the Freedom is the oxygen of the soul.

Oxygen is a plentiful and highly reactive element on the earth. Oxygen comprises about 21% of the earth's atmosphere. In its elemental form oxygen is a gas and diatomic.

The earth's crust contains a large amount of oxygen as well, primarily in the form of silicates. Many metals react with oxygen to form oxides. For example, copper reacts with oxygen to form copper (II) oxide. Iron reacts with oxygen to form iron(III) oxide (rust). Magnesium also reacts with oxygen, forming magnesium oxide.

Metalloids will also react with oxygen. Upon reaction with oxygen silicon forms silicon dioxide, the main component of sand.

Acid-base indicators are compounds that can measure the level of acidity for solutions. For example, phenolphthalein is a compound that is colorless in acidic solutions and pink in basic solutions.
