Fire spread in a building.

Ok, let's say you have a 3 story building that is very flammable and pretty much has no fire safety measures installed.

You start a fire in a room at a corner of the building on the first floor.
Will the fire spread to the room upstairs faster, or the an adjacent room faster?

How fast does the fire spread to other rooms?

it will spread up, heat rises, or to where ever there is more oxygen, you were pretty vague

setting fire to your university is HIGHLY ILLEGAL

but fun.

That would be the coolest grant proposal ever.

It will spread to the next room first. Rooms are usually separated with thin walls or doors, with lots of wood, whereas floors are separated by thick concrete slabs.
