this question asks us why most chemistry labs prefer using containers that are made out of class, so the reason to use glassware or containers made out of glass. It's because glass has many qualities that chemist prefer. One of them is the fact that it's transparent. So the entire time you're using it, you can see what's happening to your sample and what your sample is, um, undergoing, so you can see all the changes immediately on that is very good. When you are doing an experiment, you have to be able to see your sample readily so you can prepare for anything that's coming. So the transparency off class is a very important quality. And then chemists also like the fact that glass is mostly in it. Okay about that, so in that means that it will not react with most samples. So your glass container, you don't want that to react with the sample that you put in there. So glass is really good material that will not react with something easily, and that makes it's a suitable material to make a container out off to handle the sample, and then it can be heated too considerably high temperatures, not thousands off Celsius, but hundreds of Celsius. You can't heat it too much because class can melt. It has a melting point off thousands off degrees Celsius, but you can hate it very well. Ah, in the range of hundreds of says yes, without causing the container toe fall apart or a reaction between the container and the sample, you can withstand high temperatures, and then it's also easy to use and clean. So these other reasons why glasses preferred to be used to make containers in a chemistry lab. Our containers that will be used in a chemistry lab to handle samples are chemicals.
