What are the variables kept constant in Boyle's law?

Boyle's Law is an inverse relationship between pressure and volume. The kinetic theory of matter is fundamental to Boyle s Law. As the volume decreases the molecules collide more frequently...

It says that $Pprop1/V$...and thus it has NO FORMAL application to hot air ballooning...because pressure is formally constant. (Of course, as the balloon ascends, the atmospheric pressure DOES decrease...but to...

As with many early scientific discoveries, the gas law referred to as was derived independently by many scientists, but Boyle received the credit for this law probably because he was...

A basketball is held at a certain volume and pressure (constant temperature). When it hits the ground, the volume decreases and the pressure increases...and the increasing pressure springs the ball...

According to , $color(red)(v prop1/p" "$when $" "color(green)(T" & "n$ constant. According to Charle's Law, $color(red)(v prop T" "$when $" "color(green)(p" "&" "n$ constant....

was first formulated as an experimental gas law which described how the pressure of a gas decreased when the volume of said gas increased. A more formal description of...

In volume and pressure vary inversely, whereas in , volume and pressure vary directly. Consider an example, if the pressure in Boyle's law is doubled from 1.0 atmospheres to 2.0...

Yes, the point is that the quantity of gas is fixed. Since you can convert between mass and $"mol"$s using the molar mass, it doesn't matter which one is held...

tells us that for an ideal gas, at a constant temperature, volume is proportional to pressure. So doubling the volume, halves the pressure, providing temperature is kept the same....
