rise
after atoms and molecules of gases and liquids are heated, they sink?
When molecules in liquids and gases are heated they move faster
ions
All materials are formed from atoms.
The molecules in side move or spread apart
Convection in alike in both liquids and gases as, in both of them, the heated molecules being lighter rise upwards and the cooler molecules take their place.
Yes. They are able to flow.
All materials contains atoms or molecules.
Gases expand as they are heated, as do nearly all liquids. In the course of expansion, the molecules move away from each other.
They are made up of tint atoms and molecules. The atoms are so small that this period (.)is made up of about 2 billion atoms. Yes that's a lot. Thanks, Greg.S
The two elements that can be liquid at room temperature and pressure without being bonded to something else are bromine and mercury.
When a substance is heated, the extra energy makes the atoms and molecules in the substance vibrate faster and, in liquids and gases, move faster. A measure of the average velocity of such movement is called temperature. The effect of this increased movement is to change the structure of the substance. The regular order of the atoms or molecules of a solid breaks down to form a liquid - this is called melting. Further heating makes the atoms or molecules move so fast that the interactive forces between them are overcome, and they become gases - in which the atoms or molecules are free to move throughout their enclosing volume. This is called boiling or evaporation.
