Definition
| For a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship, when temperature is held constant. |

| The Celsius temperature scale is a common but non-SI temperature scale which is defined by assigning the temperatures of 0°C and 100°C to the freezing and boiling points of water, respectively. |

Term
|
Definition
| an ideal gas law where at constant pressure, the volume of an ideal gas is directly proportional to its absolute temperature. |
|

Term
|
Definition
| he combined gas law combines the three gas laws: Boyle's Law, Charles' Law, and Gay-Lussac's Law. It states the ratio of the product of pressure and volume and the absolute temperature of a gas is equal to a constant. |

Definition
| The Kelvin temperature scale is an absolute temperature scale based on the definition that the volume of a gas at constant (low) pressure is directly proportional to temperature and that 100 degrees separates the freezing and boiling points of water. |

Definition
| Pressure is a measure of the force applied over a unit area. Pressure often is expressed in units of pascals or pounds per square inch. In equations, pressure is denoted by the symbol 'P'. |

Definition
| Temperature is the property of matter which reflects the quantity of energy of motion of the component particles. There are several scales used to measure this value (e.g., Kelvin, Celsius, Fahrenheit). |

Term
|
Definition
| Volume is the quantity of three-dimensional space occupied by a liquid, solid, or gas. Common units used to express volume include liters, cubic meters, gallons, milliliters, teaspoons and ounces. Many other units exist. |
