Can every solid be changed into a liquid?
The phase, whether solid, liquid, or gas, of any substance depends upon two factors, temperature and pressure. There is a temperature and pressure at which any solid will melt and become a liquid. The great majority of solids can be melted by heating them at normal air pressure, but not all solids. Frozen carbon dioxide, for example (also known as dry ice) goes directly from the solid phase to the gas phase at normal air pressure, without ever being a liquid, as it is heated. However, with a higher pressure it can be made into a liquid.
When a solid turns directly into a gas without the liquid stage being obvious this is called?
Sublimation. The opposite is called deposition.
What Alkali metal is a liquid?
None, all are solids. Cesium and Francium are very close to being liquid at room temperature.
How do you know when a solids and liquid form a solution?
As a general rule, chemical reactions can be identified by a number of signs, including precipitation (solids floating in the liquid), effervenscance (bubbling and fizzing), heat being given off or a colour change.
How do temperature changes affect the expansion of solids liquid and gases?
Solid, liquid and gas will expand on heating. One exception is water that expands on being heated, and on being frozen into solid ice.
What is the importance of sublimation?
Sublimation can be important during the recovery of compounds that are suspended or dissolved in a fluid or a solid such as dry ice. Sublimation is the transition of a substance from a solid to a gas without passing through the liquid phase.
Can something in a solid state go into a gas state without being in a liquid state?
Dry ice changes from a solid to a gas state without being a liquid.

Which is less dense liquids or solids?
Matter being liquid or solid has nothing to do with density. These are states of matter. Ice floats on water.
When a solid changes to a gas what is it called?
Sublimation
Will bromine undergo sublimation?
Yes, bromine can undergo sublimation. At room temperature, bromine is a liquid, but if the temperature is increased above its boiling point of 58.8°C, bromine can directly change from a solid to a gas without passing through the liquid phase.
Are all insulators and conductors solids?
No, insulators and conductors can be found in various states of matter. While many are solids (such as metals being conductors and plastics being insulators), there are also liquid and gaseous substances that can exhibit insulating or conducting properties.
