Definition of Boyle’s law states:

Boyle’s law (sometimes referred to as the Boyle–Mariotte law, or Mariotte’s law) is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases. A modern statement of Boyle’s law is

The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.

## Boyle’s law examples:

**Example 1:**

5.00 L the volume of gas is at 860.0 mmHg pressure. What is its volume at standard pressure?

**Solution:**

1) Boyle’s law equation:

P

_{1}V_{1}= P_{2}V_{2}

2) equation values:

(860.0 mmHg) (5.00 L) = (760.0 mmHg) (x)

3) Multiply the left side and divide (by 760.0 mmHg) to solve for x.

x = 5.65 L (two significant figures)

The pressure units of mmHg will cancel. x is a symbol for an unknown and, technically, does not carry units. So do not write x L for x liters.

**Example 2:**

8.00 L the volume of gas is at 960.0 mmHg pressure. What volume is obtained when the pressure is 1000 mmHg?

**Solution:**

1) Boyle’s law equation:

P

_{1}V_{1}= P_{2}V_{2}

2) equation values:

(960.0 mmHg) (8.00 L) = (1000.0 mmHg) (x)

3) Multiply the left side and divide (by 1000.0 mmHg) to solve for x.

x = 7.68 L (two significant figures)

The pressure units of mmHg will cancel. x is a symbol for an unknown and, technically, does not carry units. So do not write x L for x liters.
