Explain what happens to the gas pressure in a balloon as the temperature decreases

The pressure decreases as the temperature decreases.

Explanation: As the temperature decreases, the particles of gas start moving more slowly. The particles' velocity decreases and as it collides with the wall of the container, it exerts a less force on the walls of the container. This follows on from the equation Ft = mv - mu. Less force therefore means less pressure as force and pressure are proportional according to equation Pressure = Force / Area.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
