It's called the Covection Cycle and it happens with Boiled hot water, soup or whatever, hot air balloons,clouds,and possibly volcanoes.

What is convecntion?
Convection is when heat causes a fluid to circulate around in a container.i.e. the fluid is heated at the bottom > the hot fluid rises to the surface and cools > the cool fluid then sinks again > the fluid is heated... etc.
Heat transferred by warm currents within a fluid is called what?
Convection is the movement caused within a fluid by "warm currents". The hotter fluid will rise, pushing the cooler fluid down, which then in turn gets heated, creating a continuous cycle.
What is the name of the process by which air moves and carries heat energy?
Convection is the process by which heated air (or any fluid) rises within the same medium because of its decreased density, then sinks again as it cools.
What make fluids rise and sink in a convection current?
Fluids rise and sink in a convection current due to differences in temperature and density. When a fluid is heated, it becomes less dense and rises, creating an upward flow. As it cools, it becomes more dense and sinks, creating a downward flow. This continuous cycle of heating and cooling drives the convection current.
Movement of a fluid when part of it is heated is?
convection

When do convection currents form?
Convection currents can form any time at any place, even in your stove or house. It is created when a warm fluid rises and moves, becomes cold, falls, and is heated up again. it is a cycle see!! For example, pretend you are boiling water. The fire heats up the water at the bottom, the water rises than cools when it is on the fire and is not being heated. So the cold water falls again and later heats up due to the fire. Oh yeah, warm fluid has less density, so it rises, cold fluids have a greater density, so it falls.
How do particles behave when boiling?
There is a scientific explanation to why convection, and convection currents occur. Firstly, when the fluid is heated, the particles vibrate more and move further away from each other, decreasing the density of the fluid. This lighter fluid then rises above the denser fluid. While it is rising, the newly heated fluid cools, and this makes the particles oscillate less, making them closer together, and increasing the density of that part of the fluid, making it sink. This cycle is repeated to create a convection current
In gases and liquids heat moves by convection?
yes, the hotter fluid matter rises and when it cools it falls, hence creating a convection current.
Heat transferred by warm currents within a fluid is called what?
Convection is the movement caused within a fluid by "warm currents". The hotter fluid will rise, pushing the cooler fluid down, which then in turn gets heated, creating a continuous cycle.
Why is your transmission fluid low when warm but full when hot?
That is normal. The fluid expands when heated.That is normal. The fluid expands when heated.
What is fluid that cools your body when it evaporates?
Sweat

Why is a 2003 Jeep Liberty radiator fan on while car off?
Since the fan is electric. And the vehicle is hot it will continue to cycle until cool - below 170 F As the motor cools the fan will go on and off for a little bit because as the engine cools the radiator fluid it will begin to retract, pulling hot fluid into the radiator from the motor
What happends during a convection current?
Convection currents happen in a fluid that is on top of a hot base.1. Cold fluid is heated up at the bottom2. The now hot fluid rises up and is replaced by other cold fluid3. When the hot fluid gets to the top, it flows to a side (pushed by hotter fluid rising)4. It cools down and flows to the bottom again5. REPETITION
What is a covection current caused by diffences in what?
Convection currents are caused by differences in density. Warmer fluid is less dense, so a fixed volume of the warmer fluid is lighter. Colder fluid is denser, and so heavier in a fixed volume. The colder, denser fluid presses down and falls below the less dense fluid, which floats up to the top of the fluid. Often, there is a heat source that the bottom of the container, so the fluid at the bottom, which was more dense, warms up and becomes less dense. At the same time, the fluid at the top cools down and becomes more dense, and so the cycle repeats, forming a convection current.
