So this is still adiabatic. It's insulated, but now it's constant volume, OK.

这仍然是绝热的，是隔热的，但现在它的体积是恒定的。

You're allowed Cv comes out here for this adiabatic expansion, which is not a constant volume only because this is always true for an ideal gas.

绝热过程写下,这个式子是因为它对理想气体都成立，并没有用到等容过程的条件,只用了理想气体的条件。

Yes, exactly, it's adiabatic, right constant pressure.

对，没错，它是绝热的。
