Gases. Their molecules are already the farthest apart compared with solids and liquids, and small changes in temperature causes these loose molecules to absorb the kinetic energy of the heat and expand. If not bound by a container, the gas can expand indefinitely into the atmosphere.
In the gaseous state of matter, the molecules of a substance are most free to move about as there is little attractive forces between the neighboring molecules.
plasma
plasma is most common in the universe outside of earth plasma is the most common state of matter
Hot springs or geysers are created when groundwater gets heated by hot intrusive rocks and can ascend via fractures in the crust. In the most extreme case so called phreatomagmatic eruptions take place. When magma ascends and reaches groundwater at shallow depths, the resulting steam expands dramatically and fractures the overlying rock thus producing a conical hole in the ground. These volcanic craters are referred to as maars.
Plasma is the most common state of matter. Plasma is a mixture of atoms and ions and electrons where electrons are mobile with respect to the ions and atoms. For example, electrons in conducting metals constitute a Plasma mixture; ionized gas is a plasma mixture. The key to Plasmas is the presence of mobile charges in a mixture. The mixture can be charge balanced, (plus and minus charge equal), but some charges are mobile, not bound. For example atoms in a crystal may be bound in the crystal structure but their electrons can move within the crystal structure, thus creating a an electron plasma.
Most matter EXPANDS when heatedmost matter expands when heated
The individual particles vibrate/move faster. The matter as a whole expands.
When matter is heated the particles in the matter gain energy and begin to move or vibrate more depending on the state in which the matter is currently in. If the heat provided is significant enough they can change state too. Hope that was what you were looking for!
gas expand more than liquid and liquid expand more than solid.
I would have to say Gas.
Most substances expand when heated.
Most substances expand when heated.
Only one liquid expands when heated and thats water the most common liquid.
Matter expands when heated, because molecules move farther apart.
Lead...
Most materials expand when heated.
MOST matter expands as it gets hotter.
