Does the flask contain the same more or fewer gas molecules compared to before it was heated?

The same if it was closed (i.e cork).
If it was open, it would be less, as gas usually expands as it is heated, and it depends on the amount of heat, the pressure, temperature etc.

What is the evidence that molecules of g as large spaces between them compared to liquids and solids?
well,.....for gas when it is heated the molecules spread and have power and become into vapor, and compared to liquid and solid it is larger because liquid is a not a solid and does not have a fixed shape, and a solid has a fixed shape and gas can be put into anything!
Why do molecules move when heated?
So when molecules are heated, the heat is so intense that they have to move around for them to cool down.

What are your rocks and soil heated by?
Rocks and soil are heated by two things, atoms and molecules. when they get heated they vibrate and sends heat to other atoms or molecules in the same substance until the whole thing is heated. The energy comes from the sun, but the atoms and molecules really heat them.

new molecules starts to form
What happens to a fluid when it heats?
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
Why sugar dissolves fast on heating?
When sugar is dissolved in any solvent (i.e. Water or Milk), its molecule tries to adjust themselves between the molecules of the solvent... When the solvent is heated the distance between the molecules is increased and the sugar molecules are easily dissolved as compared to when the solvent is cool or at normal temperature...
What vibrates in objects?
