中文: 摘要根据改进的硬球混合物模型,正确预测了氨基酸分子的烃链在电解质水溶液中的标准偏摩尔体积随电解质浓度的变化关系,并证实了“氨基酸分子中CH和CH3基团的标准偏摩尔体积之和是CH2基团标准偏摩尔体积的2倍”这一假定。更详细... 英文: Understanding concepts of the molar volume of gas, then learning som...
Molar volume of gasesMoleThe mole and Avogadro's number are two important concepts of science that provide a link between the properties of individual atoms or molecules and the properties of bulk matter. It is clear that an early theorist of the idea of these two concepts was Avogadro. ...
A certain volume of a gas (diatomic) expands isothermally at20∘Cuntil its volume is doubled and then adiabatically until its volume is again doubled. Find the final temperature of the gas, givenγ= 1.4 and that there is 0.1 mole of the gas. Also calculate the work done in the two ...

A substance whose mass is F, and the ratio of M to M is called the amount of the substance (also called moles), = M. For example, M=404x10-3kg = H2 = 2 hydrogen. The volume Vm of a molar substance is called the molar volume. The molar volume of a gas depends on temperature ...
volume. At low pressure, gas volume is directly proportional to number of moles; therefore, the composition of air as stated can also be interpreted as 21mole% oxygen. Because temperature changes at low pressure produce the same relative change in the partial volumes of the constituent gases as...
