Hello,
I noticed that some reference books classify filter paper as material, but some reference books classify it as apparatus. So is the filter paper a material? As i know, material is the thing that  will disappear or change after the experiment. Since the filter paper will use up after experiment, is it classify as material?

[Patrick Chai Teck Khiong]

Yes. Since the filter paper will used up in the experiment and discard after used, we classify it as materials.
