In a still room, smoke from a candle will sometimes rise only so far, not reaching the ceiling. Explain why.
Step 1 of 3
In still room,warm air collects at the top and cool air collect at bottom.the air satisfied by temperature because density depends on temperature.the smoke rises to the point where it has the same density as the air,and stops.smoke from a candle will sometimes rise only so far, not reaching the ceiling. This phenomenon is used for the blanket of smog that can be trapped over cities such as Los Angeles.hence in still room smoke from a candle will sometimes rise only so far,not reaching the ceiling.. Or The smoke is like a hot air,is less dense than surroundings and buoyed upward.it cools with the contact with the surrounding air and it will become more dense,when density matches the surrounding air,smoke buoyancy and weight matches then rising ceases.
