on解析：Rusting是铁与氧气和水发生化学反应生成铁锈（主要成分是氢氧化铁和氧化铁），生成了新的物质，是化学变化。其他选项a)沸腾是物理变化；b)溶解是物理变化；d)熔化是物理变化。22.c)Toabsorbsunlightforphotosynthesis解析：Chlorophyll是植物进行光合作用的色素，其主要功能是吸收太阳光，特别是红光和蓝光，为光合作用提供能量。23.b)Mantle解析：地幔（Mantle）位于地壳之下，是地球内部的主要部分，主要由硅酸盐岩石组成。它在高温高压下呈塑性状态，可以缓慢流动，是板块构造运动的主要驱动力。虽然固态，但具有可塑性。24.c)Lightisessentialforplantgrowth.解析：实验对比显示，有阳光的植物生长优于无阳光的植物。这表明阳光（光）对植物生长是必需的。25.c)Ampere(A)解析：国际单位制（SI）中，电流的单位是安培，符号为
