الضغط وقياس الضغط
Gas pressure is caused by force exerted by gas molecules colliding with the surfaces of objects. Although the force of each collision is very small,…
قوانين الغازات
Through experiments, scientists established the mathematical relationships between pairs of variables, such as pressure and temperature, pressure and…
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…
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…
الحسابات الكيميائية للعناصر المتفاعلة والغازات
Chemical stoichiometry describes the quantitative relationships between reactants and products in chemical reactions. In addition to measuring…
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
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…
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
Thus far, the ideal gas law, PV = nRT, has been applied to a variety of different types of problems, ranging from reaction stoichiometry and…
الجمع بين كابنوجرافي الحجمي وضغطي بليثيسموجرافي لقياس علاقة بنية-وظيفة الرئة
Tools to measure lung and airways volume are critical for pulmonary researchers interested in evaluating the impact of disease or novel therapies on…
أسلوب عيانية تناظرية لدراسة العمليات هيدرودينامية الجزيئية في كثافة الغازات والسوائل
An analog, macroscopic method for studying molecular-scale hydrodynamic processes in dense gases and liquids is described. The technique applies a…
Polymerizations الإثيلين عن طريق المفاعلات الضغط الموازية وتحليل الحركية من سلسلة البلمرة نقل
We demonstrate a method for high-throughput catalyst screening using a parallel pressure reactor starting from the initial synthesis of a nickel…
