Shifting temperature. If its colder, the harder it will get because the particles will compress together. If its warmer, the substance will liquify (melt) or even turn into gas because the particles move apart from each other.
radioactive decay
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
physical
A specific type of physical change is a change in phase. This involves the transition of matter from one state (solid, liquid, gas) to another without a change in chemical composition or bonding.
The diagram needs to be seen to know what the state of change is. Not seeing the diagram makes people not able to know what the change would be.
chemical change
A change of state is a molecular change.
A chemical change results in new compounds being formed. In a chemical change, the atoms rearrange to form different chemical substances with new properties. This is different from a physical change, where the substance remains the same but changes in appearance or state.
radioactive decay
chemical
Condensation
these change causes the change intermolecular forces which results into change in state of that compound or new compound is formed excclusively depending on the change done
Each city and state has its own job market and unemployment rates so there is no way to really answer this questions because the answer who change based on the field, type of job, time frame, and other factors that impact the results for your search of a particular city or state.
physical
Type your answer here..the shape and volume
physical... the matter itself does not change. That would imply that a chemical change is taking place
no- melting is not a chemical change. It is merely a change in state of the same substance not a chemical reaction.
