Question

When researchers cool a gas, which of the following has occurred?

Select all that apply.


Mass of the gas is reduced linearly as pressure decreases
Cooling stops once absolute zero (-273K) is reached
Velocity and spacing of particles is reduced
Volume of substance decreases relative to temperature decrease

Answer 1

Explanation:

Velocity and spacing of particles is reduced and Volume of substance decreases relative to temperature decrease. 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.
