What is a sidewalk warmed by the heat of the sun a chemical or physical change?
It undergoes a physical change because the matter that makes up the sidewalk does not change. THe side walk goes through a chemical and physical change because the heat makes it constrict by shacking the particles just like it happens with food
Side walk is warmed by the heat of the sun physical or chemical?
The sidewalk being warmed by the heat of the sun is a physical process. The sun's rays transfer heat energy to the sidewalk through radiation, causing the molecules in the sidewalk to vibrate more rapidly and increase in temperature. This is a physical change as no new substances are being formed in this process.
Is sunshine warming the sidewalk a chemical change?
No. The sidewalk is still a sidewalk. All of the same molecules are still there in the same arrangement.
Is origami a physical or chemical change?
Origami is a physical change because it involves the folding and manipulation of paper without altering its chemical composition.
A physical change that does not produce a new substance is called what?
A physical change that does not produce a new substance is called a reversible change. This means the change can be undone by reversing the process, such as melting or freezing.

Is melting ice by spreading salt on an icy sidewalk a chemical or physical change?
physical change because by adding salt you are lowering its melting point thus can melt the ice at low temperature.
What is a sweeping change?
broad
Is sidewalk a concrete noun?
Yes, the noun 'sidewalk' is a concrete noun, a word for a physical thing.
Is salting the ice on the sidewalk a chemical change?
Yes. The melting point of salt solutions is lower than that of pure water.
Is cracks on a sidewalk next to a tree physical or chemical weathering?
Cracks on a sidewalk next to a tree are primarily caused by physical weathering. The tree roots grow and expand, exerting pressure on the sidewalk, which eventually causes it to crack. This is a mechanical process rather than a chemical one.
Is salting the ice on a sidewalk a chemical change?
yes

No. The sidewalk is still a sidewalk. All of the same molecules are still there in the same arrangement.
Over time how might the grass growing up through a crack in a sidewalk affect the sidewalk Use the terms and ldquophysical weathering and rdquo and and ldquochemical weathering and rdquo in your answe?
The grass growing through a crack in a sidewalk can contribute to physical weathering by exerting pressure on the concrete as the roots expand, potentially widening the crack. Additionally, the roots can facilitate chemical weathering as they release organic acids that can weaken the sidewalk's structure over time. Ultimately, this combination of physical and chemical weathering can lead to further deterioration of the sidewalk.
Is crumple a chemical change or physical change?
Crumple is a physical change.
