Select all that apply. which of the following statements about charles's law are true? a. real gases may be expected to deviate from charles's law at high pressures. b. ideal gases may be expected to deviate from charles's law at high pressures. c. real gases may be expected to deviate from charles's law near the liquefaction temperature. d. ideal gases may be expected to deviate from charles's law near the liquefaction temperature.

Answer is:

A. Real gases may be expected to deviate from Charles's law at high pressures.

C. Real gases may be expected to deviate from Charles's law near the liquefaction temperature.

At high pressure gas molecules are close to one another and near the liqueffaction temperature energy is very low.

Charles' Law (The Temperature-Volume Law) - the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature:  

V₁/T₁ = V₂/T₂.  

When temperature goes down, the volume also goes down.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
