Dalton's law of partial pressures

例句：

1. 1. The gases in the air are influenced by the laws of thermodynamics and the behavior of gases at different temperatures.
   空气中的气体受到热力学定律和不同温度下气体行为的影响。
2. 2. The law of partial pressures states that the concentration of a gas in a mixture is directly proportional to its partial pressure.
   部分压强定律表明，一种气体在混合物中的浓度与其部分压强成正比。
3. 3. In this case, the law of partial pressures applies because the concentration of oxygen in the air is higher than the concentrationof nitrogen.
   在这种情况下，部分压强定律适用，因为空气中氧气的浓度高于氮气。
