Does a phsical change or chemical change affect the matter in an object?
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
Is sugar changing to alcohol a physical or chemical change?
Anything changing to a substance with a different identity is undergoing a chemical change.
Temperature a substance will change from liquid to gas?
Yes, only if the temperature of a substance is increased.
What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
What are the differences between a chemical and physical change?
A physical change doesn't change the molecular properties of a substance. Some examples of physical changes include tearing paper, or the evaporation of water. A chemical change does change the molecular properties of a substance. For example, if you burn wood you get leftover carbon, and CO2 is also released; no longer does the wood have the same molecular properties or structure.
As heat is added to a substance undergoing a phase change the temperature remains constant because the energy is being used to?
Overcome intermolecular forces
Why the temperature remain constant altough heat is absorbed from surrounding?
That will not happen unless matter is undergoing a phase change and the temperature you are measuring is that of the matter undergoing the phase change.
A substance that speeds up a chemical reaction without undergoing a permanent change itself is?
A substance that speeds up a chemical reaction without undergoing a permanent change itself is a catalyst.
What is true for a substance undergoing a phase change?
It will change state from a solid to a liquid to a gas and finally to a plasma.
Substance that speeds up a chemical reaction without undergoing a permanent change -?
Catalyst
What does thermochromatic mean?
it refers to a substance undergoing a reversible change of colour when heated or cooled
Why does the temperature of body remain steady when the body is undergoing a change in state?
5620
How does specific heat of a substance relate to temperature change?
A substance with a high specific heat will easily change temperature.
How does the specific heat of a substance relate to temperature change?

How do you identify the change of state a substance is undergoing?
through it's boiling, melting, and freezing point.
