Objects

The video explores the concept of objects and systems, using the kilogram and Avogadro Project as examples. It discusses the difference between treating something as an object or a system, depending on the scale and the question being addressed. The video also includes a simulation comparing salt and sugar in water, highlighting the importance of understanding systems at a microscopic level to see differences. The key takeaway is that the approach to studying objects or systems depends on the specific problem being solved.

What are the observable differences between salt and sugar when dissolved in water?

How do the properties of a system relate to the interactions of its constituent parts?
