Do molecules rise or sink after they are heated?
Rise
What are kitchen sink faucets made of?
Kitchen sink faucets can be made of a variety of materials. Some are brass, zinc, copper, lead, tin, plastic, or marble. Many are a combination of the above materials.
What materials sink?
anything denser than the medium it is suspended in.
What happens to thermal energy when you mix hot and cool water together?
Since hot water is less dense that cold air the hot water will rise and the cold would sink then it keeps doing this in a circular motion 'till the thermal energy reaches to thermal equilibrium.
How does zero gravity change the shape of the flame?
A flame has the classical teardrop shape because of convective air flow; as the hot, thin air rises (less dense things rise, while more dense fluids sink), the combustion process is carried up with it. Cool dense air flows in below it, providing fresh oxygen to the flame. In zero-G, hot things don't rise and cold things don't sink. (With no gravity, which way would be "rise" and which way would be "sink"?) Hot gasses expand - but there's no gravity to pull cold, dense material down and allow the hot, thin gasses to rise. So in zero-G, a flame is circular - until it goes out, snuffed by the carbon dioxide that gathers around it. With no convection, fresh air can't get to it. If you wanted to burn a candle in the space station, you would need to provide a tiny fan to blow the CO2 away and blow fresh air in to the flame. Of course, this would be an INCREDIBLY STUPID THING TO DO, because oxygen is precious and expensive; it has to be flown up by rockets!
Why do warm materials rise and cooler materials sink?
If materials get warmer, it expands; therefore the density (which is mass divided by volume) decreases.
How does temperature affect air movement?
the hot air will rise and the cool air will sink
The tendency for warm air to rise and cool air to sink results in what?
The tendency for warm air to rise and cool air to sink results in convection currents. As warm air rises, it cools and then sinks back down in a continuous loop, creating circulation patterns in the atmosphere. This process helps distribute heat and moisture around the Earth.
When happens when cooler air and heated air interact?
The cool air will sink and the warm air will rise.
What will rise and what will sink?
a stone will sink and a feather would rise
Why does cool rock materials sink when convection takes place in the mantle?
Cool things always sink (because they are more dense) and hot things always rise (because they are less dense) in convection. It does not matter if it is rock, air, water, metal, wax, oil, etc., convection always works the same.

Does heated air rise or sink?
rise
Do molecules rise or sink after they are heated?
Rise
What is the opposite of sink?
The opposite reaction of to sink (in liquid) is to float.However the opposite motion sink (move lower) would have the opposite rise.
The tendency for warm air to rise and cool air to sink results in?
