تطبيقات قانون الغاز المثالي: الكتلة المولية والكثافة والحجم
The volume occupied by one mole of a substance is its molar volume. The ideal gas law, PV = nRT,  suggests that the volume of a given quantity of gas ...

خليط الغازات- قانون دالتون
Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each gas ...

النظرية الجزيئية الحركية: المسلّمات الأساسية
The ideal-gas equation, which is empirical, describes the behavior of gases by establishing relationships between their macroscopic properties. For ...
النظرية الجزيئية الحركية وقوانين الغاز
النظرية الجزيئية الحركية وقوانين الغاز
The test of the kinetic molecular theory (KMT) and its postulates is its ability to explain and describe the behavior of a gas. The various gas laws ...

السرعات الجزيئية والطاقة الحركية
The kinetic molecular theory qualitatively explains the behaviors described by the various gas laws. The postulates of this theory may be applied in a ...
الانصباب والانتشار
الانصباب والانتشار
Although gaseous molecules travel at tremendous speeds (hundreds of meters per second), they collide with other gaseous molecules and travel in many ...
الغازات الحقيقية- الانحراف عن قانون الغاز المثالي
الغازات الحقيقية- الانحراف عن قانون الغاز المثالي
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and empirical and ...
