a gas is placed inside a very cold box . The gas molecules transfer heat to the walls of the box. Which best describes what happens to the gas as it cools down?

As the gas cools down, particle movement slows down with it, and so does the temperature of the gas. This is because the more heat or thermal energy a gas has, the faster the particles move. This is why absolute zero, or 0 degrees Kelvin is defined as zero particle movement, because it has zero energy.
Hope this helps
