Yes, smoke and hot gases tend to move downward due to their high temperature and lower density compared to the surrounding air. This creates a buoyancy effect, causing them to sink. In indoor environments, this can lead to the accumulation of smoke and hot gases near the ground.

Surface indications of the presence of geothermal activity?
Surface indications of geothermal activity include hot springs, fumaroles (vents emitting steam and gases), geysers, mud pots, and mineral deposits such as sulfur and silica. These features are caused by the movement of magma and hot fluids beneath the Earth's surface heating up water and gases, which then emerge through cracks and vents in the ground.
How could fossil fuels have an affect on the temperature of the planet?
Burning fossil fuels releases greenhouse gases like carbon dioxide into the atmosphere. These gases trap heat from the sun, leading to a warming effect known as the greenhouse effect. This can contribute to global warming and climate change.
What are 3 surface indications of the presence of geothermal activity?
Hot springs or geysers releasing steam and hot water. Fumaroles emitting gases such as sulfur dioxide. Ground surface deformations like uplift or subsidence due to underground pressure.
How does the composition of gases change as you travel up through earths atmosphere?
As the gases go higher in the atmosphere they start to compose or join together at some point which causes them to change since there is mixture of more than one gas, sometimes they form a different element when certain gases form
What are three presence of geothermal activity?
Geysers: Hot water and steam periodically erupt from the ground. Hot springs: Natural pools of warm water heated by geothermal activity. Fumaroles: Openings in the earth's crust that release steam and gases.
Why was the smoke moving downwards when you put the dry ice in the hot cup of coffee?
Because of condensation between Ice and the hot coffee.
What is it called when hot smoke gases up and go to the chimmeny?
This process is called "flue gas exhaust," where hot smoke gases from a fire or combustion process are directed up a chimney or flue to be released into the atmosphere.
How about smoke does it have mass does it occupy space why?
Yes, smoke is a combination of hot gases and particulates (e.g. soot, fly ash).
In what direction do hot and cold gases move?
Hot gases move upwards as they are less dense and lighter, while cold gases move downwards as they are more dense and heavier. This is due to the natural process of convection, where warmer air rises and cooler air sinks.
What would cause the burning in your respiratory system?
Usually by breathing in smoke, very hot air, or toxic gases.
Why at a campfire the ash from the burning wood goes up into the air instead of downwards even though gravity causes things to fall downwards?
Because the tiny ash particles ride in the flow of hot air rising from the fire ... same as the smoke particles do.
If you have to move through smoke to get out what can make it easier?
Breathing through a rag or a wet rag can help. So can dropping to the floor and crawling. Smoke, as with hot gases, tends to rise.
Is carbon monoxide more soluble in hot or cold water?
Carbon monoxide is more soluble in cold water compared to hot water. This is because gases tend to dissolve better in colder temperatures.
Did old cars run on smoke?
They ran on woodgas. The product of partially burning wood and passing the smoke over burning hot charcoal is a gas containing Carbon monoxide and hydrogen and some other gases.
Why do flames rise even though gravity pulls things downwards?
Flames rise because the hot gases they consist of are lighter than the surrounding air and therefore experience buoyant forces that push them upwards. Gravity still acts on the flames, but the buoyant force is stronger, allowing them to rise.
Why does the mass of an object get smaller after it gets burnt?
Because the smoke you see during the burning, and the hot gases that you don't see, carry part of the mass away from the object.
What makes hot-air balloon drift downwards?
Balloons start to lose altitude when the air inside the envelope cools off. In order to keep the balloon aloft the balloon pilot uses a burner to heat up the gases inside.
