What does Η mean here?

Η is the feminine singular definite article, so it means the.

It matches φυσαλίδα, which is a feminine singular noun. So:

• η φυσαλίδα = the bubble

Greek articles change for gender, number, and case, unlike English the, which always stays the same.

Why is it φυσαλίδα? What form is that?

Φυσαλίδα is the nominative singular form of the noun φυσαλίδα.

In this sentence it is the subject, the thing doing the action:

• Η φυσαλίδα αέρα = the air bubble

Because it is the subject, Greek uses the nominative form.

Why is it αέρα and not αέρας?

Because αέρα is the genitive singular of αέρας.

Greek often uses the genitive where English uses of. So:

• φυσαλίδα αέρα = literally bubble of air
• natural English: air bubble

So αέρα here shows what kind of bubble it is.
