Chapter 9 - Gas Laws Flashcards
What is Gay-Lussac’s law of combining volumes?
When measured at constant temperature and pressure, the volumes of gases taking part in a chemical reaction show simple whole-number ratios to one another.
What is Avogadro’s law?
When measured at the same temperature and pressure, equal volumes of different gases contain the same number of molecules.
What is the molar volume of a gas at 25C at 100kPa?
24.79L
How do we write the alternative of Boyles law?
P1V1=P2V2
What is Boyles law?
For a given quantity of gas at a constant temperature, the product of its volume, V, and its pressure, P is constant.
What is Charles law?
For a fixed quantity of gas at a constant pressure, volume increases linearly with temperature.
What is the absolute temperature scale also called?
The Kelvin temperature scale or thermodynamic temperature scale.
What is the symbol for absolute temperature?
T.
How do we write Charles’s law?
V1/T1=V2/T2
How do we write the combined gas law?
P1V1/T1=P2V2/T2
What does the combined gas law contain?
Both Boyle’s and Charles’s law.
What is Gay-lussac’s pressure, temperature law?
P1/T1=P2/T2
What is the ideal gas law?
PV=nRT where R is the universal gas constant, 8.314 JK-1mol-1
