Gases tend to deviate from the ideal gas law at
MrRa [10]

Answer:

<em>Gases tend to deviate from ideal gas law at </em><u><em>high pressures and low temperatures.</em></u>

Explanation:

The main statements from molecular kinetic theory to describe an ideal gas is that 1) the gas particles occupy a neglictible fraction of the total volume of the gas, and 2) there is not force of attraction between gas particles.

HIgh pressure means that the gas particles will be forced  closer to each other, making that the mean distance between the particles be realtively more important and their volume less neglictible. This is a violation the first assumption described above.

Since the temperature is directly related to the kinetic energy, and the latter with the movement of the particles (average speed), low temperatures lead to the molecules being less independent of each other, i.e. the forces between the molecules will count more . This fact constitutes a violation of the second principle established in the first paragraph.

In <u>conclusion</u>, <em>high pressures and low temperatures tend to deviate gases from the ideal gas law.</em>

Boiling water is a physical change, because it is changing state of matter, there is a controllable temperature change, and you can change it back.

Which of the following BEST describes the process of evolution by natural selection?
svlad2 [7]

Answer:

<em>The correct option is B)  a gradual change of the traits of a species over time</em>

Explanation:

The theory of natural selection explains the gradual changes which occur in the population of a species over time. According to natural selection, those organisms which are better adapted to live in an environment survive and pass on their traits to their offsprings. As a result, the traits of a species tend to change over time through the process of evolution. Evolutionary changes do not occur rapidly, instead, they can take many years to occur.
