What happens to a solid when is heated?
A substance in the solid phase will typically expand when heated. Most substances when heated sufficiently will melt into a liquid, assuming that they do not combust or sublimate.
What kinds of changes in substances are always physical change?
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.
Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
What happens to the volume of most substances as they are heated?
the volume of the solid would go down , thus making the solid into a liquid.
Solid liquid or gas expand the most when heated?
Ice (frozen water) and Water (below 4 oC) expand when cooling. This is exceptional! Other substances, also Water (above 4 oC) expand when heated.
Does water expand or contract when it changes from liquid to solid?
when a liquid turns into a solid it contracts
Change from a solid to a liquid is called?
1. in most pure substances, melting occurs at a specific Temperature called the melting point. 2. the change of state from liquid to solid is called freezing (solidification) 3. the change from a liquid to gas is called Condensation.
What are some characteristics for a physical change?
A physical change is a change that can be reversed easily and no new substances are made. Examples are state changes ie. solid to liquid or liquid to gas.
Change from liquid to solid?
is when the solid is hard then the word is Melting to change to liquid
How are the state changes of similar to the states changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
How are the state changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
Do most solids expand when cooled?
Generally speaking, substances have the least amount of surface area as a solid, as they are heated they form a liquid and expand, as this is heated it forms a gas and expands more. *Assuming pressure is constant **Water is the only substance to expand as it freezes
