(5分)某日,京沪高速上,一辆槽罐车与一辆大货车相撞后翻倒在地,槽罐车上满载的液态氯气快速泄漏。由于与事故发生地相距300m的地方是一个村庄,因此,此次液氯泄露极可能导致人员的伤亡。

信息链接:①氯气为黄绿色气体,②有强烈刺激性气味,③在常温下,氯气可溶与水,在高压下可以液化,并装入槽罐车中进行运输,④氯气密度为3.21 g/L(空气为1.293 g/L),⑤氯气既可与氢气等非金属单质反应,⑥也可与钠、镁等金属单质反应,⑦还能与熟石灰反应生成次氯酸钙(Ca(ClO)2)、氯化钙和水。

请根据以上信息,回答下列问题:

⑴①~⑦中,属于氯气物理性质的是                (填序号);
