Some rise and some sink what is it?

why does the lava sink or rise?

it will rise it will rise

sink

rise because of it's density

gas fumes rise. In general, a 'gas' will rise. But 'gasoline' fumes are heavier than air, so they sink. Of course they are 'fumes' so they will be easily circulated.

A heat-sink is needed to dissipate the wasted power without any undue temperature rise. The effectiveness of a heat sink is measured by the watts dissipated per degree of temperature rise.

causes warm air to rise and sink

It tends to rise because it is warm air

Air rises at the equator.

Your lungs expanding and closing.

Pressure variations

rise because the salt water is denser... i think...

Bourne believed that an object would float or sink at will as long as he could manipulate the effect's of buoyancy which control and object to sink or float.

It causes convection currents because there is hot air and cold air.The hot air will will rise and the cold air will sink. then the cold ari will rise and the hot air will sink. it all changes.For instance, the hot air after it rises will sink down adn become cold air. The cold air after it sinks, it will become hot air and rise.

Day and Night the sun a swimmer a tide

Likely a slight clog in your sink trap or drain pipe.

If an object has air in it than no it will not sink in water because air is less dense than water so it will rise in water.

HOT rises COLD sinks

belts sink and zones rise

Some kinds of submarines use ballast tanks, they are tanks on the subamarine which the submarine fills with water to make it sink or filled with air to make it rise.

It forms when cirrus or cirrostratus is warmed gently from below. This causes air to rise and sink inside the cloud. Some of the ice crystals change into water vapor, and gaps appear.

global wind patterns.

No air or any form of gas will always rise to the surface (as a bubble)

The man density more then water these means the mans are have some density more then water.

cooler air masses sink and warmer air masses rise.

it will have cracks and it will start to sink and rise

The cool air will sink and the warm air will rise.

It takes on water to alter its density to greater than that of water, allowing it to sink, pumping the water out reverses the state, allowing it to rise.

Fluorine is a gas, so it will neither sink nor float, it will expand to fill whatever container it's in. If bubbled through water, it will quickly rise to the surface then dissipate.

Heated air will rise, cooled air will sink.

because warm air has less pressure then what cold air has

Because warm air is less dense then cool air.

cold air sinks as denser - warm air rises

Yes, dinghys sink. Some are more likely to than others.

Buoyant means: Tending to float on a liquid or rise in air or gas

The higher the saline content in water the heavier the water. This causes it to sink towards the bottom and water with lower levels will rise to the top. It will remain so unless stirred vigoriouly and often. Many animals live, and thrive in this setting, such as salt marshes, springs, also some ponds and lakes.

It is to do with to volume and mass.

B. Hot gases or liquids rise and cold substances sink.

Well some people will sink because they are very muscular, because muscle has a lower bouyancy than fat- they sink. Some people may not be EXXTREMLY muscular- but if you let the air out of your lungs you will not have as much air to keep you floating upwards like a bubble does, and will in turn sink.

Many soaps are more dense than liquid water, causing them to sink.

It doesn't set, you just can't see it sometimes. As the earth turns the moon appears to rise above the horizon and sink below it. This is known as moon rise and moon set. There is no specific time it happens.

Asiatic Theory According to the Asiatic theory of doctor Leopoldo Faustino, the islands were formed through the process of diastrophism. this explains the movement of earth that caused some parts either to rise or to sink. this happens with the folding, faulting and warping of the earth

A submarine changes its buoyancy using ballast tanks. They are either filled with water or air to rise or sink, respectively.

Heat changes the density of a fluid - relatively hot fluids rise and cold fluids sink causing a current

The warmer fluids is less dense, and also the kinetic energy of the molecules increases.

No, some sink.

Some objects float on water because these objects are lights and some objects sink in water because these objects is heavy

Mercury has a double sunrise because when the sun rises a bit, an orbital effect makes it sink down and rise again.

In simple terms the sun heats some area more than others. The warmer air masses will rise because they are less dense, and more air will have to move in to replace it. Air that is less heated will sink, and spread out when it reaches the ground.
