four mechanisms that cause air to rise are orographic lifting,frontal wedging, convergence,and localized convective lifting
The surrounding air has to be colder than the warm air in order for it to rise. And in result, the cold air sinks. xD
Lhs - air reaches low pressure system, forces over mountain, warm/cold/occluded front, convection
the heat given of from mechanism or the primary source the sun
cold air enters a region
Solar wind, mountains, and fronts
heat,evaporation and condensation
Solar wind , mountains 🏔 and fronts.
Smoke comes from a fire at it's base. Hot air rises so the smoke is carried upward by the heated air
Heat speeds up molecules, this causes the particles to rise
head pressure
"Lift" is the force that acts opposite to gravity. If 'lift' can be made to exceed the weight of the craft, then the net vertical force on it is directed upward, and the craft can rise.
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.
Heat can cause air to rise :)
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.
What is in yeast to cause it to rise
soar
Because colder air is forcing it upward.
They don't. It is the other way around. Cold fronts commonly cause cumulonimbus. Such clouds form when the atmosphere is unstable, meaning that a parcel of air, when given an upward nudge, will continue to rise on its own. A cold front provides that upward nudge to trigger cumulonimbus development.
The word rise is a noun form, a word for an upward movement; an increase in size, amount, or strength; an increase in the power or influence of someone or something; a word for a thing.Examples:The rise of the sun tomorrow is at 6:46 AM.It's not nice to say things just to get a rise out of him.'The Rise and Fall of the Third Reich' by William L. Shirer
there are actually four and they are frontal wedging, mountain lifting, convergence, and lifting by heat.
For pitching, the spin can cause the ball to either rise, drop, curve, or do a combination of those things.
hot air
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.
Yeast must have three things in order to rise, moisture, food, and warmth.Ê These 3 things can alter the rising times for yeast.ÊÊ The amount of yeast also determines how fast your baked good will rise.Ê You can decrease your rise time by using rapid-rise yeast.
