If we mechanically squeeze a gas into a smaller volume, what happens to the pressure and temperature? a. the pressure and temperature both increase, but we can't predict how much each one will change. b. the pressure increases and the temperature decreases. c. only the pressure increases.

If we mechanically squeeze a gas into a smaller volume the pressure and temperature will increase but we can't predict how much each one will change.

Option A

Explanation:

When we squeeze a gas or a material, a force acts upon it making it to compress which increases the pressure subsequently as tension and compression is always accompanied by pressure.

The temperature of gas also increases as work is done due to transfer of energy which alters the existing temperature.

the independent variable, or the one that is intentionally manipulated is the speed.

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.
