a low density solid
gas or a liquid
Solids. (Anything that isn't a liquid or a gas)
It depends. Some solids will first melt (change to a liquid) and not change to a gas until still more energy is added. Some solids will change directly to a gas by a process called sublimation. Pretty much all solids have a pressure range (from zero pressure up to their triple point) where they will only sublimate.
take the shape and volume of its container, as the gas particles are free to move and spread out to fill the available space. This is due to the lower intermolecular forces between gas particles compared to solids and liquids.
mixtures can be formed by physically putting two or more substances together. Mixtures can be formed between solids and liquids, solids and solids, liquids and liquids, solids and gas, liquids and gas, gas and gas
Three signs of physical change are change in shape, change in size, and change in color.
liquids turn into gas and solids don't and gas evaporates
Liquid and gas can flow and change shape to fit their containers, while solids have a fixed shape and volume. Liquids and gases can also be easily compressed or expanded, which is difficult for solids to do.
The particles of gas have more energy and are less tightly packed than particles in solids. This allows gas particles to move freely and change position easily, while solid particles are held in a fixed position by strong intermolecular forces.
A gas cannot go through non-porous solids.
A solid is transformed in a liquid by melting; some solids are transformed directly in a gas by sublimation.
