If a gas with a specific gravity of 1.3 is released in a room, will it be more likely to be found near the ceiling or near the floor?
A) Near the ceiling because its specific gravity is greater than 1.
B) Near the floor because its specific gravity is greater than 1.
C) It would be found at both the ceiling and the floor because a gas with a high specific gravity would fill up the room.
D) The specific gravity of a gas does not affect its position in a room relative to other gases.
