A change of state occurs when a substance changes from one of the four states of matter to another. The four states of matter are solid, liquid, gas, and plasma. A common example would be an ice cube melting from solid to liquid. Another example would be when dry ice (frozen carbon dioxide) goes from solid directly to gas in a process called sublimation.
What else can I help you with?
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
Which process changes water into a gaseous state?
The process that changes water into a gaseous state is called evaporation, where water is heated and transforms into vapor or steam.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What two changes of state does this process involve?
In order to know what two changes of state are involved in a process one needs to know what the process is.
What is the best definition of condensation?
Condensation is the process by which a gas or vapor changes into a liquid state due to a decrease in temperature or an increase in pressure. It is the opposite of evaporation, where a liquid changes into a gaseous state.
What is meant by harmful changes?
Harmful changes refers to anything that was done that was detrimental to the goal. The opposite of harmful changes would be helpful or positive changes, which would move you closer to your desired state.
What is meant by liquid state?
The liquid state is meant as a state of matter.
What is meant by state?
state
What is vaponzation?
There seems to be a typo in your question. Assuming you meant "vaporization," it refers to the process where a substance changes from a liquid or solid state to a gas or vapor state. This usually occurs when the substance is heated to its boiling point.
What is meant by the phrase 'work in progress'?
Something is a 'work in progress' if it is in a state that is not in a complete, polished state but is still undergoing changes. The term may be used to describe products as well as individuals, if they are presently changing or somehow incomplete.
How substances changes from one state to the other state?
through changes of energy
Why are changes of state chemical changes?
They aren't; a change of state is a physical change
Are state changes chemical or physical changes?
Physical Changes
What is meant by succession changes over time?
To have something done
What Matter changes state because of?
Matter changes state because of pressure and temperature.
When water is boiled it changes?
When water boils it changes from a liquid state to a gaseous state.
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.
