What is a unique property of water Describe the property and explain the chemical or physical reason that causes water to have the property?
Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.

Explain whether water is a cause of either chemical weathering physical weathering or both?
Water can cause both chemical and physical weathering. In chemical weathering, water can react with minerals in rocks to break them down into new substances. In physical weathering, water can seep into cracks in rocks, freeze, and expand, creating pressure that breaks the rock apart.
Explain the similarities and difference between physical weathering and chemical weathering?
Physical weathering involves the breakdown of rocks into smaller fragments without altering their chemical composition, typically through processes like freezing and thawing or abrasion. Chemical weathering, on the other hand, involves the decomposition of rocks through chemical reactions that change their composition, such as oxidation or dissolution by acidic water. Both processes contribute to the overall breakdown of rocks, with physical weathering primarily affecting the size and shape of rocks, and chemical weathering changing their chemical structure.
Explain different chemical weathering and mechanical weathering?
Chemical weathering rocks may decompose or dissolve and at the same time change in compostion through a certain chemical process to form residuals materials. Mechanical weathering happens when rocks disintegrate or breaks down into smaller pieces through physical forces. (rain, snow, freezing)
How to explain weathering?
Weathering is the process by which rocks and minerals are broken down into smaller pieces through exposure to natural forces like water, wind, and temperature fluctuations. There are two main types of weathering: mechanical weathering, which involves physical breakdown of rocks into smaller fragments, and chemical weathering, which involves chemical reactions that alter the composition of rocks. Over time, weathering can contribute to the formation of soil and shape the Earth's surface.
Explain how you can tell whether a chemical reaction has taken place?
A chemical change or reaction happens if new substances are formed. there may be a change in temperature so the reaction mixture may heat up or cool down. it also might change colour, give off bubbles of gas or fumes and you also might hear fizzing or a gas might explode.
Explain the difference between chemical properties and physical properties?
Chemical properties describe how a substance can form new substances by undergoing chemical reactions, like flammability or reactivity. Physical properties describe characteristics that can be observed without changing the substance's identity, like color, density, or melting point.
Is the property of copper a physical or a chemical property explain?
The property of copper being a good conductor of electricity is a physical property because it can be observed without changing the chemical composition of copper. It is a characteristic based on the arrangement of electrons in the copper atoms.
Must new substances be formed when you observe a chemical property explain?
Yes , it should or else it is a physical property
If Brand X aluminum foil is thicker than Brand Y is thickness a physical property or chemical property explain?
Thickness is a physical property without any relation with chemical composition or chemical changes.
Is twisting a wire chemical or physical change explain?
It is physical. The wire changes shape, but it is still made of the same materials.
17 Explain how color can be classified as both a physical property and as one indication of a chemical change?
Color can be classified as a physical property because it can be observed without changing the chemical composition of a substance. However, color change can also indicate a chemical change when it is a result of a reaction that alters the molecular structure of the substance, leading to a new chemical identity. In this case, the color change is a visual representation of the chemical transformation that has occurred.
Is it a chemical or physical change when heat is put over sugar?
its physical change.to explain,the conversion of solid to liquid is physical
Can you explain the difference between physical changes and chemical changes?
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
Why is energy necessary to chemical reactions and describe some common sources of energy.?
Explain why energy is necessary to chemical reactions, and describe some common sources of energy.
When the banana, berries, water, and hot dog are blended, does a physical or chemical change occur?
both physical and chemical change occur
What makes elasticity a physical property?
The concept of elasticity is a physical property because force can mutate a physical item and then when that force is removed and elastic object returns to its original form.æ Using elasticity to explain non physical phenonmena is a misnomer.
Does food go thought a chemical physical or both change during digestion Explain?
Both
