我想知道matter与substance在化学上意思的区别,
我的书里面有这么几句"The world around us is made up of matter.Matter is anything that occupies space and has mass.Everthingwe see,touch,taste,or smell is matter."
"One particular type of matter is called a substance .Iron,water and air are examples of substances."
因为我觉得上面说的substance已经包含了一切物质了,我想不出matter里还可能有什么.所以可否以此解释一下matter与substance在化学上意思的区别,

matter此处专指无生命的各种物质,研究其物理性质、结构、组成元素并加以抽换、操纵、还原,例如:将牛奶变成奶油、铅变成黄金
化学物质(Substance):为自然存在的或人工制造的化学元素和它的化合物.包括加工过程中为保持其稳定性而使用的添加剂和生产过程中产生的杂质,但不包括任何一种在不影响其稳定性或改变其成分的情况下就可被分离的溶剂.
◆配制品(Preparation):是指所有两种或两种以上的化学物质的溶液或混合物.
◆物品(Article):由一种或多种物质和(或)配制品组成的物体.在生产过程中,它被赋予了特定的形状、外观或设计,比它的化学成分有更多的最终功能.例如纺织品、汽车、电子芯片等.
