Q. What is convection?
A. Convection is: The circulating of heat through a liquid or gas by the motion of currents within that liquid or gas.

23 And there was a row of building round about in them, round about them four, and it was made with [mebashsheloth,
boiling places, cooking hearths] boiling places under the rows about.
24 Then said he unto me, These are the places of them that [bashal..boil, to boil (up), sod, sodden, seethe, bake, roast, ripen, bring forth ripe, be ripe] boil, where the ministers of the house shall [bashal..boil, to boil (up), sod, sodden, seethe, bake, roast, ripen, bring forth ripe, be ripe] boil the sacrifice of the people. Ezekiel 46:23,24
..Water can be boiled..Food is cooked in boiling water.

31 He maketh the [metsulah..shady place, deep, deep place of water, deep place of mud, depth] deep to [rathach..
make to boil, to cause to bubble up, (to) boil] boil like a pot: he maketh the [yam..pool, large body of water, lake, river, sea] like a [sir, ciyr..pan, pot, caldron, to boil up] pot of [merqachah..an ointment kettle, seasoned with spice, pot of perfumes, well] ointment. Job 41:31..
Evaporation is a form of boiling..Water can be boiled..Deep water can be boiled..Mud can be boiled..Deep mud can be
boiled..Large bodies of water can be boiled..Lakes of water can be boiled..The water of the sea can be boiled..Water from wells can be boiled..Water can be boiled in pans and pots and caldrons..Water bubbles..When water boils water forms bubbles..When mud boils, bubbles appear in the mud.

3 And utter a parable unto the rebellious house, and say unto them, Thus saith the LORD God; Set on a pot, set it on, and also pour water into it:
4 Gather the pieces thereof into it:
5 Take the choice of the flock, and burn also the bones under it, and make it [rathach..make to boil, to cause to
bubble up, (to) boil] boil well, and let them, [bashal..
boil, to boil (up), to boil, sod, sodden, seethe, bake, roast, ripen, bring forth ripe, be ripe] seethe the bones of it therein. Ezekiel 23:3-5..Water can be boiled..Bubbles rise up from within boiling water..Water bubbles..Water bubbles up.

2 As when the melting [esh..burning, hot, fiery, flaming, fire] fire [qadach..kindle, be kindled, inflame, burn]
burneth, the [esh..burning, hot, fiery, flaming, fire] fire causeth the [mayim..water, waters] waters to [baah..to swell, to swell out, seek up, be sought up, cause to boil, to gush over] boil, to make thy name known to thine adversaries, that the nations may tremble at thy presence! Isaiah 64:2..Heat is released from flames of fire..Fires must be kindled..Heat causes water to swell (expand)..
Heated water swells (expands)..As water is boiling, water within the water, rises up..Convection..Heated water rises and cold water sinks..Job 6:15-17

Convection..As water is boiling, the heated water rises up, and the cooler water sinks to take its place, and currents of water called convections are set up within the water..
Water that is boiling, bubbles up and over, and out of the pot..Water can be spilled..Spilt water..Spilt water can be
wiped up with a cloth..2 Kings 2:13..Dry materials absorb water..Water that has been soaked up by a cloth disappears
into the cloth.

Absorption..Wet cloths can be dried by the fire (in the sun)..Leviticus 2:14.

The heat of the sun causes water to evaporate (dry up) into the air..Evaporation.

CONVECTION.
A science experiment with boiling water for adult christians.

You will need. 1 notepad, 1 pen or pencil, to record your science experiment, 1 pot, 2 large cold spoons, leave one cold spoon in the freezer till needed, water to reach half way up the pot, a source of heat (stove top), and 1 tea towel.

Place your cold water in the pot, put the pot upon the top of your stove, turn up the heat, and watch the water in the pot.

Almost immediately tiny bubbles begin to appear in the water, and rise from the bottom of the pot, to the surface
of the water where they pop. Tiny bubbles remain on the bottom of the pot, and other bubbles which are now in-creasing in size continue to rise to the surface of the water, where they form clusters of bubbles of different sizes and pop. A noise begins to come from the pot where the water is being heated.

Now hold the bottom of the cold spoon over the top of the water that is being heated; resting the handle on the side of the pot, you will see vapour rising from the pot, and droplets of water collecting on the bottom of the spoon.

The water on the bottom of the spoon is condensed water, it is water from the pot that has risen into the air and has condensed (turned into water droplets) on the surface of the cold spoon. This is called condensation. Cold causes water to condense (drop) out of the air.

Later, when you wipe your spooon with the tea towel, you will see that the water has been absorbed by the dry cloth. This is called absorption, and when you hang your tea towel out on the line to dry, heat will cause the water in the tea
towel to evaporate (dry up) into the air. This is called evaporation.

If you look down into the bottom of the pot you will see bubbles of water bursting at the bottom of the pot. While at the surface of the water, clusters of bubbles are beginning to whirl about, and vapours are rising more rapidly from the pot, the bubbles get bigger, and rapidly whirl on the surface of the water, and the bubbles break, as the water is carried up and down and around within the pot. This is called convection. If you listen to the water, you will hear the bubbles pop.

Now let the water keep boiling rapidly, and watch the level of water in the pot begin to drop as the water boils away,
finally, before the water has totally gone, the pot fills with bubbles, and the bubbles burst as the vapour rises up, and vanishes into the air, leaving the pot, totally dry. Quickly remove the pot from the stove, and don't forget, to turn off the heat.

Drawing water out of the air: Take your cold spoon out of the freezer and hold it upright, within a few moments,
invisible water vapour will condense (come) out of the air and form tiny droplets of water on the surface of the spoon.

Ripening (cooking) unripe fruit: If you cook a piece of unripe fruit in boiling water for ten to twenty minutes
depending on your taste buds, the fruit with a little sugar or seasoning will be softened (ripened, cooked) enough for you to eat.
