What is the formula of Boyles law?

Answer 1

The mathematical equation for Boyle's law is PV = k or you could say P1V1=P2V2.

P IS the pressure of the system.

V is the volume of the gas.

k is a constant value representative of the pressure and volume of the system.

**It just states that pressure and volume are inversely proportional when temperature is held constant (does not change). In other words, as volume increases pressure decreases and vice-versa (when temperature is constant).**

Also, an easy way to remember all of the laws (Boyle's, Charles', and Gay-Lussac's) is to remember one equation: The Ideal Gas Equation, which happens to be PV=nRT. P=pressure, V=volume, n=number of moles, R=constant (varies with certain units, for example, when using torrs or mm Hg it would equal 62.4), and T=temperature. You can make basic assumptions from this equation, for example, you know that when temperature is held constant that if pressure increases volume must decrease (which happens to be Boyle's Law).

Answer 2

1. A more correct name is Boyle-Mariotte law.

2. This law is a relation between pressure and volume at constant temperature. The equation is:

pV = k

where p is the pressure, V is the volume, k is a constant specific for the system.

Answer 3

The formula for Boyle's law is P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume of a gas at constant temperature.
