Transcript
Rising
Water
Temperature goes up and so particles move faster = pressure increases
Vacuum:
Gases exerting pressure from an area of high pressure to an area of low pressure.
Temperature drops because the candle went out
Low pressure inside the cup and the high pressure outside of the cup
Particles slow down=pressure decreases
Materials
Bowl Plate
Candle
Water
Matches
Glass Cup
Cupping
Results
- Water rises in the cup and drains from the bowl plate
- Bubble action at the end
- Water vapor condenses
- A little carbon monoxide is produced
China
Egyptians
Greece
Bubbles!
BUT WHY
Candle makes air molecules get all excited and bounce around, as a result some escape
Carbon Monoxide
As temperature increases, pressure increases and vice versa.
Gay-Lussac
CH4 + O2--> CO2 + H2O
heat and light
Not enough oxygen to react completely to form carbon dioxide and water
Combustion reaction:
Incomplete combustion reaction:
Candle=Combustion=not enough oxygen=death if you sniff it
Water Vapor
Some water entering the muggy cup atmosphere changes to gas sate because the molecules get KE
