Are physical changes reversable?
Physical changes can be reversible or irreversible depending on the nature of the change. For example, melting ice is reversible as it can be frozen again, while cutting a piece of paper into smaller pieces is irreversible.
Where is Physical weathering most dominant in?
Physical weathering is most dominant in regions with extreme temperature changes, such as deserts and high mountainous areas. Freeze-thaw cycles, where water seeps into cracks in rocks and freezes, breaking them apart, are common mechanisms of physical weathering in these environments.
What climates would physical weathering most readily occur in?
Physical weathering is most likely to occur in climates with frequent temperature changes, such as in deserts and mountainous regions. These areas experience daily temperature fluctuations that contribute to the expansion and contraction of rocks, leading to physical weathering processes like freeze-thaw cycles and exfoliation.
What is the type of matter change in which matter stays the same and no new substances are formed?
A physical change is a type of matter change in which the substance's chemical composition remains the same, and no new substances are formed. Examples of physical changes include changes in state (solid to liquid), changes in shape, or changes in size.
Can silicon undergo a physical and chemical change?
Yes, silicon can undergo physical changes such as melting and crystallizing. It can also undergo chemical changes when it reacts with other elements, forming compounds like silicon dioxide (SiO2) or silicon carbide (SiC).
Is sugar dissolving in water a chemical change?
no....it is a physical change as it is only changing its state and it is reversable. somtimes it is reversable
Is setting clsy is an reverseble or irrevessable Changes?
if it is not in the oven it is reversable
What are signs a physical change has occured?
change in the form -in general can be indicated for the physical form. The substance may dissolve or its stage may change. If the change is physical, it should be reversable.
What is the differences between physical and chemical change in tabular form?
physical change are reversable
Are physical changes reversable?
Physical changes can be reversible or irreversible depending on the nature of the change. For example, melting ice is reversible as it can be frozen again, while cutting a piece of paper into smaller pieces is irreversible.
Is burning a wooden match physical or chemical?
Chemical, it isn't reversable.
Are all physical changes accompanied by chemical changes?
Not all chemical changes are accompanied by a visible physical change. Most chemical changes however will be accompanied by a physical change.
How is freezing mercury a reversable physical change?
During freezing the chemical nature of mercury remain unchanged.
Which physical processes is most frequently responsible for changes in oceanic tides?
Gravity is most responsible for the changes =)
Physical processes is most frequently responsible for changes in oceanic tides?
Gravity is most responsible for the changes =)
What is the effect of physical changes?
Physical changes do not change the properties of the substance. You can get back the original state of the substance in most cases by reversing the physical process.
Is a physical change a change that you make something but you can change it back to its normal shape?
yes. a chemical change/reaction is irriversable, whereas a physical change/reaction is reversable.
