So, du plus p dV is less than zero.
因此,du加上pdV需要小于零。
Vdp So dH is just du plus p dV plus V dp.
所以dH等于du加上pdV再加上。
Sometimes you see this written when you see p orbitals, one is written as plus, one is written in minus.
有时候你们看p轨道时会看到,一个写成正号一个写成负号。
H=qp The u plus p V. Delta H is equal to q V.
括号里面的就是H,等于u+pv,Δ
Remember the equation of state for Van der pV=nRT Waal's gas is not pV is equal to nRT, but p plus the attraction term.
记住范德瓦尔斯气体的状态,方程不是,而是p加上一个吸引项。
du external dV minus T surroundings dS is less than zero.
加上压强p,du,plus,p,乘以dV减去环境温度T乘以dS小于零。
V So it's minus T dV/dT at constant p, plus V.
负的T乘以恒定压强下dV/dT,再加上。
