Which of the statements about gases is not correct?
Gases have low densities compared to solids and liquids of equal mass.
The total kinetic energy of the gas is not affected by collision
Molecules of the gas are in constant motion
Gases are highly soluble in water at high temperatures
설명
The statement that is not correct about gases is Gases are highly soluble in water at high temperatures.
Gases are not highly soluble in water at high temperatures. The solubility of gases in water decreases as the temperature increases. This is because the kinetic energy of the gas molecules increases as the temperature increases. The increased kinetic energy of the gas molecules makes it more difficult for them to be dissolved in water.
