2. No

  • It will rise, because the little fish takes up the space of the water and the water has to take up some other space.
  • Experiment: Accept any meaningful planning, for instance bicycle pump that cannot be pushed in completely if the opening is closed.

Mass as opposed to weight : Mass gives an indication of the amount of matter, while weight indicates how strongly the earth attracts an object. Mass remains unchanged, while weight is influenced by the location on earth - e.g. high up in the atmosphere it is less.

Assignment 4

Matter occupies space

Study the following sketches and answer the questions that follow:

1. Is it possible for two objects to occupy the same space simultaneously? (Yes / No)

_____________________________________________________________________

2. Examine the sketch of a fish in an aquarium:

_____________________________________________________________________

  • Do the fish and the water occupy the same space?

_____________________________________________________________________

  • What would happen to the water level if the fish were to produce young?

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

_____________________________________________________________________

When we examine the above sketches, it is obvious that two objects cannot occupy the same space at the same time. The reason for this is quite simple: Each object requires its own space. Another deduction that we could make is that matter that is displaced by some other substance occupies other available space.

Matter has volume and mass

If you drink all the cold drink in a cold drink can, the can is not left empty. The original contents (cold drink) have been replaced with air! The same space is therefore occupied by another form of matter! Sometimes we speak of the contents of the tin, meaning the matter inside the tin. The space inside the tin that is occupied by matter (cold drink or air, in this instance) is referred to as volume . To some extent, therefore, volume and content are synonymous.

Plan an experiment to prove that air occupies space.

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
