Comprehension Passage
Gases are one of the states of matter distinguished by their ability to fill any container, assuming both its shape and volume. The behavior of gases is governed by several key laws that relate to their pressure, volume, temperature, and amount. Boyle's Law demonstrates the inverse relationship between pressure and volume at constant temperature. Charles' Law shows the direct proportionality between volume and temperature at constant pressure. Avogadro's Law links the volume of a gas to the amount of substance in moles at a constant temperature and pressure. The Combined Gas Law integrates Boyle's and Charles' laws, and the Ideal Gas Law (PV=nRT) combines these relationships providing a comprehensive equation for predicting the behavior of an ideal gas under various conditions.
What is Avogadro Law?
1
At constant volume, pressure of a fixed amount of a gas varies directly with the temperature.
2
Equal volumes of all gases under the same conditions of temperature and pressure contain equal number of molecules.
3
At constant pressure, the volume of a fixed mass of a gas is directly proportional to its absolute temperature.
4
At constant temperature, the pressure of a fixed amount of gas varies inversely with its volume.
