Humpback whales (座头鲸) are among the world’s most endangered whales. The main threats humpback whales face are strikes from ships and getting caught in fishing and waste equipment. Recently, scientists have developed a technology-powered mapping tool to prevent ships from hitting whales in areas off America’s west coast. The system is called Whale Safe. It uses equipment placed in the ocean to identify the presence of whales in the surrounding area.
Whale Safe was recently launched to the north in San Francisco Bay. There is a problem in the bay with ships hitting whales. Wildlife officials reported that a humpback whale washed ashore in the San Francisco Bay with injuries suggesting the animal was killed in a ship strike. It was the fifth whale to be killed by a ship strike in the area in 2022. However, the actual number of whales killed by ships is likely much higher because the bodies of the dead animals are rarely discovered.
The system uses three methods to identify and protect several different whale species. First, it uses flotation devices — known as buoys (浮标) — to record sounds the whales make. Second, it uses computer models to process current and historical ocean data to predict where the whales are most likely to be. Third, it permits trained observers and citizens to report whale sightings through a mobile app. The tool also records shipping activity and ship speeds. The collected data is then sent by satellite to scientists who examine it and seek to provide guidance to ship operators.

用坩埚钳夹住铁丝并点燃末端的火柴梗,待火柴梗快燃尽时,将它由上而下缓慢伸入集满氧气的集气瓶中,避免火柴消耗较多集气瓶内的氧气;
(2)实验Ⅱ为测定空气中氧气含量的实验,在瓶内加少量水并将水面上方空间分为5等份,接下来的实验步骤依次为:弹簧夹夹紧橡皮管、点燃燃烧匙内的红磷后,立即伸入瓶中并把塞子塞紧、冷却到室温,最后打开弹簧夹读数。所以顺序是:③②①;
(3)①在白磷开始燃烧时,反应放出大量的热,集气瓶中的空气膨胀,压强增大,集气瓶中的水一部分被排出,液面下降;最后熄灭冷却至室温时,集气瓶中的压强减小,在外界大气压的作用下,水进入集气瓶,液面上升,因此集气瓶内水面的变化情况是先下降,后上升,故①正确;
②实验前集气瓶里没有装水,会使瓶内的气体逸出,实验最后产生的实际值会大于理论值,故②错误;
③集气瓶的容积为150mL,在加入50mL水后剩余的容积为100mL,而氧气约占空气体积的五分之一,所以反应完全并冷却后进入集气瓶的水的体积为20mL,所以最终集气瓶内水的体积约为70mL,故③错误;
④由实验后,水并没有充满整个集气瓶;过量的红磷不能在其中继续燃烧可知,剩余气体不是氧气,所以该实验还可以得出空气是混合物的结论,故④正确;
故选①④。
【解析】
【详解】A、实验中所用红磷应过量,否则不能将装置内氧气耗尽,会导致实验结果偏小,不符合题意;
B、用酒精灯点燃红磷,应将燃烧匙快速伸入集气瓶中,防止装置内气体受热膨胀逸出,导致实验结果偏大,不符合题意;
C、红磷燃烧一段时间,熄灭后,应等冷却至室温打开弹簧夹,否则气体受热膨胀,占据了一定的体积,会导致实验结果偏小,不符合题意;
D、红磷燃烧消耗氧气,氧气约占空气体积的,故正确操作将观察到消耗的气体与剩下的气体的体积比约为1:4,符合题意。
故选D。
7. 空气是一种宝贵的自然资源。下列有关空气的说法不正确的是
