What did rutherford learn about the atom from his gold-foil experiment?

1 answer:

4 0

Hi there!

Rutherford's experiment showed that the atom's nucleus did have a positive charge. The α particles' trajectory was altered when it went through the gold foil, which, in turn resulted in the discovery of the atom's positive charge.

I hope this helps!

physical change because even though gas formation was observed, the water was undergoing a state change, which means that its original properties are preserved

Explanation:

The boiling of water is a physical change because the original properties of the water is preserved.

A physical change is the one that alters the physical properties of matter.
This kind of change is easily reversible as the water can be cooled back.
No new kinds of matter is produced in this kind of change .
The molecules of the matter still retains their property after.

During the boiling of water, intermolecular bonds called hydrogen bonds between the water molecules are broken. This makes the individual molecules free.
