Answer:
Its properties remain unchanged as it is undergoing physical changes.
Explanation:
Hello.
In this case, since aluminum foil is made up of aluminum leaves having a 0.2-mm thick it is widely known that is deformed when wrinkled due to its tiny average thick. Moreover, when cut half over and over again smaller pieces are obtained every time it is done. Nevertheless, even when its shape and size can be modified via physical actions, its properties remain unchanged because cutting is a physical change which is not affecting its chemical composition.
Best regards.
Answer:
it moves faster when heated
Answer:
Also called superposition. When overlapping waves produce a wave with an amplitude that is the sum of the individual waves. When overlapping waves produce a wave with an amplitude that is less than the sum of the individual waves.
Explanation:
Answer:
Explanation:
Hello,
In this case, for us to compute the final volume we apply the Boyle's law that analyzes the pressure-volume temperature as an inversely proportional relationship:
So we solve for 
by firstly computing the initial pressure:
Finally, we can compute the work by using the following formula:
