The physical law that the volume of a fixed mass of gas held at a constant pressure varies directly with the absolute temperature.

物理定律，在不变压力下，一定质量的气体的体积与绝对温度的变化成正比。

The celebrated Boyle's law (1662) states that, the temperature being kept constant, the pressure and volume of a gas are inversely proportional.

还提出了著名的玻意耳定律（1662年）：恒温下，气体的压力与体积成反比。

So what happens then we're going to use the ideal gas law. So it's approximately delta u plus delta nRT. That's a constant. That's a constant.

我们现在要应用理想气体物态方程,这个近似等于ΔU加上Δ,这是常数，这是常数。
