# Gas Laws

### Gas Laws: terms

Question | Answer |
---|---|

For a given mass of gas at constant temperature, the volume of the gas varies inversely with pressure | Boyle's Law |

the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant | Charles Law |

the law that describes the relationship among the pressure, temperature, and volume of an enclosed gas | Combined Gas Law |

a measure of how much the volume of matter decreases under pressure | Compressibility |

at constant volume and temperature, the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases | Dalton's Law of Partial Pressures |

molecules tend to move toward areas of lower concentration until uniform without | Diffusion |

the process that occurs when a gas escapes through a tiny hole in its container | Effusion |

pressure of a gas is directly proportional to the Kelvin temperature if the volume is constant | Gay Lussac's Law |

the rate of effusion of a gas is inversely proportional to the square root of its molar mass | Graham's Law of Effusion |

R=8.31 x (LxkPa/Kxmol) | Ideal Gas Constant |

PV=nRT, which describes the behavior of ___ gases | Ideal Gas Law |

the contribution each gas in a mixture of gases makes to the total pressure | Partial Pressure |
