What must be present in order for asubstance to changev from one state of matter to another?
For a substance to change from one state of matter to another, energy must be added or removed to break or form intermolecular forces. The temperature and pressure conditions must also be appropriate for the desired state change to occur, such as melting, boiling, or freezing.
How can substance changes from liquid to gas?
For a substance to change from liquid to gas, heat energy must be added to increase the molecules' kinetic energy, breaking the intermolecular forces holding them together. This allows the molecules to move more freely and spread out, turning the substance into a gas. This process is known as evaporation or boiling, depending on the specific conditions.
What 2 conditions that density has to meet in order for it to be used to identify a mystery substance?
Density must be a characteristic property of the substance, meaning it is unique to that substance and doesn't change with the amount or shape of the sample. Additionally, the density value of the substance must be compared to known values to determine a match, so accurate measurement and comparison methods are essential.
What must you know if a chemical change occurs?
fizzingcolor change (of course, this exempts artificial coloring)odorformation of precipitateproduction of gasformation of new substance (elemental bonding)
Even if you change the shape and amount of a substance it's stays the same?
This statement is incorrect. Changing the shape or amount of a substance can alter its physical and chemical properties. For example, breaking a substance into smaller pieces can increase its surface area and affect its reactivity, while changing the amount of a substance can change its concentration and impact its behavior in a reaction.

What must be added or taken away for a change in the state of matter to occur?
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
How does state of matter relate to temperature?
States of matter could be said to be Solid Liquid and Gas. As a substance transits or passes through these states of matter then the amount of energy increases. It takes energy to separate the particles and break bonds as the substance goes from Solid to Liquid and then more inter-particular bonds must be broken to form the Liquid. Temperature does not change during the change of state as the energy is absorbed by the bonds. Temperature continues to increase once the new state is formed.
Is there loss of heat during change of state of matter from liquid to gas?
Yes there must be achange;but heat is required to change liquid state into gaseous state.
How do you know when something has gone through a physical change?
A physical change refers to a change in the physical state or appearance of a substance without altering its chemical composition. You can observe a physical change by noting changes in color, shape, size, texture, or state of matter (solid, liquid, gas) of the substance. Additionally, physical changes are usually reversible.
What must happen for a change in state of matter to take place?
Change Of Temperature. For Example; Water Freezes At Zero Degrees Celsius. Frozen Water (Ice) Melts Into Water (Usually) At Twenty Degrees Celsius; Try Holding It In Your Hands Or Mouth For About Five Minutes. Water Can Then Evaporate At Higher Temperatures Into Steam (Which Is Usually On Windows And Mirrors After You Get Out Of A Shower.
To get matter to change you must always do what?
you can't change matter
A compound that can be separated by electrolysis must be in which state of matter?
A compound that can be separated by electrolysis must be in the LIQUID state of matter.
What is required to change matter from on state to another?
you must reach its melting point or freezing point or boiling point.
What must be added or taken away in order for matter to changes states?
Energy must be added or taken away.
When a substance undergoes a physical change what does not a change?
The chemical make up of a substance does not change. It must remain the same combination of atoms or molecules to be considered only a physical change.
When a physical change in a sample occurs which does not change?
Substance in the material Remain the same
