Some physical properties change, but the substance keeps its identity.
When dealing with these kind of questions, understand that the keyword here is physical change. Thus, all options that says no physical properties change are WRONG. So this leaves us with only 2 answers left. However, this is a physical change, no chemical change. Thus, the substance will keep its identity and not change.
Answer:
it is an ideal gas because all of the substances that it has are good for us and won't affect us in any way

rock is the correct answer
Explanation:
Answer:
Supersaturation is possible
Explanation:
As a solution of solid in water cools, the dissolved solid would begin to reappear as the solution is now supersaturated at that lower temperature.
When the temperature of a solution is increased, more solute are able to dissolve in solution. A supersaturated solution is one that contains more than the required amount of solute needed to saturate the solution at that particular temperature.
The IR spectrum of aldehyde compound will not show evidence of hydrogen bonding. The Infrared (IR) spectrum involves the interaction of infrared radiation with matter. It is used to study and identify chemicals and their properties. Evidence of hydrogen bonding is not shown due to lack of molecular contact.
