Why a flame always points upwards?
The combustion reaction heats the air, causing the air molecules to vibrate faster and move further apart. This means that the gas in the flame expands and becomes less dense than the air around it, causing it to rise.
Why excretion in planaria is also called flame cell system?
in planaria excretion takes place through diffusion,as will as have special excretory system made up of many tubule called protonephridia.protonephridia give rise to branches have special kind of cells called flame cells.flame cells is nucleated have a cavity,in the centre of cavity there are cilia.cilia undulate itself look like a flickering candle that,s why it,s calld flame cells.flame cells and tubules are full of fluid,containing waste matter dissolve in it.flame cells excrete the waste through excretory pore called nephridiopore,by undulating their cillia.
Why does magma rise through the crust above it?
Pressure builds in the magma chamber forcing it upward through faults in the crust
Could property of magma that cause it to be forced upward towards earth surface?
Because magma is less dense than the surrounding solid rock, it is forced upward toward the surface. When magma reaches the surface and flows from volcanoes, it is called lava.
What is the overall rise in earth's average temperature called?
The rise in temperature is called Global Warming. This global warming of the earth is causing Climate Change. These two things are not the same thing.
Why fire does not comes downward?
The heat generated by the fire warms surrounding gasses and they rise, pulling the flame up.
Why does smoke rise quickly?
Smoke comes from a fire at it's base. Hot air rises so the smoke is carried upward by the heated air
Upward force on a bird's wing?
It is called Lift. The difference in pressure above and below the wigs as a bird moves through the air produces an upward force that causes the bird to rise.
What is a weird fact about magnesium?
Pouring water on conflagrated magnesium only accelerates the fire and may even cause an explosion (really just a rise in flame).
What is the name of the upward force that enable a bird to fly?
It is called Lift. The difference in pressure above and below the wigs as a bird moves through the air produces an upward force that causes the bird to rise.
Why does fire go upward?
Flames are the gasses of combustion, heated to the point of glowing. Hot gasses, being less dense and therefore lighter than cold gasses (surrounding air) rise upward until they are redirected by some solid object.
Why does smoke travel upward?
The smoke particles from a fire are carried up by hot air. Hot air has the tendency to rise because it has less density than normal air.
Flames of fire rise even though gravity pulls things downwards?
Yes. Fire goes upward precisely because Earth's gravity pulls things downward. The fire is lighter (less dense) than the air that replaces it, so the air pushes the hot air from the fire upwards.
Is Rise up o flame a round song?
Yes It. Is.
Flames of a fire rise even though gravity pulls things downwards?
The air above and around the flame heats up, expands and moves up. Cooler air below the flame moves in to take its place, heats up, rises and the process repeats itself.
How do you calculate the force that make an object mass rises to an distance vertically?
1). First of all, in order to make an object rise at all, an upward force must be applied to it, and the force must be greater than the object's weight. 2). If an upward force exactly equal to the object's weight is applied to it, then the object can "hover" wherever you put it, as if it is weightless, but it can't rise. 3). If the upward force is greater than the object's weight, then the object can rise to any desired height. It will continue to rise, and its speed will increase, as long as the upward force continues. 4). When the upward force stops, then the object will continue to rise, but it's upward speed will begin to decrease. When the upward speed decreases to zero, the object stops rising and begins to fall. It's downward speed then increases continually, until it hits the ground.
Four letter word for flying upward?
soar
