Answer is: Formed by adding 5 g of sugar to 1 L of water.

Sugar and water make a homogeneous mixture (the same proportions of its components throughout any given sample).

Boiling pure water is physical change of substance (from liquid to gaseous state).

Combining three hydrogen atoms to every nitrogen atom is chemical reaction (new substance is formed): 3H₂ + N₂ → 2NH₃.

Compressing carbon under high pressure is physical change.

when you started the activity, the can was open to the air outside tge can. how did the air pressure inside the can compare to t
aliya0001 [1]

The air pressure inside the can is lower compared to that of outside air pressure.

Explanation:

  • In general, the air pressure of an already opened can will be the same as the outside pressure.
  • Since the can is evacuated and remain as vacuum, so there will be no pressure difference in it.
  • If the can opens, air inside the can push the top and escapes to the outside.
  • This is due to high pressure experienced outside the can compare to that of lower pressure inside the can and this may even cause can to collapse itself.
