What must be present in order for asubstance to changev from one state of matter to another?
In order for a substance to change, a certain temperature or pressure must be reached.
How can energy be conserved if a substance must gain or lose thermal energy to change state?
Heat is a form of energy. It is just being transferred to the temperature bath (air, water, whatever). It hasn't been destroyed.
How does substances change from state to state?
In order to form a compound from elements, you would definitely need a chemical change. A compound is the chemical combination of two or more substances that cannot be separated by physical means. Examples of compounds are table salt (NaCl), sugar, and water.
Is the sublimation of carbon dioxide exothermic?
sublimation doesnt nessicarily have anything to do w/ temperature. it is observed in substances such as CO2 (Carbon Dioxide) which have high vapor pressure and low intermolecular force. i take no responsibility for any harm done to u or whoever tests this in some krazy way reading my response to this question....
Even if you change the shape and amount of a substance it's stays the same?
By changing the size, shape, or amount of a given substance, a physical change is being exerted. A physical change is a change in which the molecular structure of the substance remains the same. For a substance to be considered "changed", a chemical reaction must take place resulting in a reconfiguration of molecules. For example, with enough heat, wood undergoes a chemical reaction, converting it to carbon. Chipping a log with a hatchet, on the other hand, would entail a physical change.
What must be present in order for asubstance to changev from one state of matter to another?
In order for a substance to change, a certain temperature or pressure must be reached.
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.
To get matter to change you must always do what?
you can't change matter
What must occur to the heat energy of an object in order of a phase change of the state of matter?
heat is added
What is required to change matter from on state to another?
you must reach its melting point or freezing point or boiling point.
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 must be added or taken away in order for matter to changes states?
Energy must be added or taken away.
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
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.
How does energy play a part in matter changing state?
Energy directly relates the the temperature of a substance. The more energy in is proportional to a higher temperature. The inverse is also true. When changing states you must use the formula Q=ML where Q is the energy in Jules, M is the mass in grams and L is the latent heat (fusion or vaporization) of the substance. This determines how much energy is needed to change state.
