What else can I help you with?
Does water has a fixed volume?
No, it does not. The volume of water changes according with it's temperature. Water, unlike other substances, it has a minimum volume at 4 degrees Celsius.
How long non biodegradable substances last?
Examples are plastics, metal and glass. Dangerous chemicals and toxins are also non-biodegradable, as are plastic grocery bags, Styrofoam (polystyrene), and other similar materials.
What is the purpose of an indicator in science?
An indicator usually means a substance which changes colour depending on what other substances are present. The most common type are acid/alkali indicators such as litmus, which is red in acids and blue in alkalis.
What substances influence other molecules without being changed themselves?
I think what you are looking for is a catalyst. A catalyst lowers the energy or activation for a reaction, allowing it to happen faster. During the reaction nothing actually happens to or changes the catalyst.
What particle is transfered when 2 substances are rubbed together?
The outer surfaces of all substances encountered in our daily lives are covered in electrons. When two surfaces are rubbed against each other, electrons may be transferred from one surface to the other, creating a static charge on each of the substances, one positive and the other negative.
How are the state changes of similar to the states changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
How are the state changes of water similar to the state changes in most other substances?
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
How substances changes from one state to the other state?
through changes of energy
What causes chemical and physical changes?
Chemical changes occur when substances react with each other to form new substances with different properties. Physical changes, on the other hand, involve alterations in the state or appearance of a substance without changing its chemical composition. Both types of changes are driven by factors like temperature, pressure, and exposure to other substances.
What happens when matter is changed physically?
It means that although it changes, no new substances are formed. Examples of such changes are melting and other state changes, and dissolving.
Is ability to react with other substances chemical or physical?
The ability for a substance to react with other substances is a chemical property, as it involves changes in the substance's chemical composition. Physical properties, on the other hand, relate to characteristics such as color, shape, and state of matter, which do not involve changes in chemical composition.
Which type of science studies how substances change?
Chemistry studies how substances change through various reactions and interactions with other substances. It examines the composition, structure, properties, and changes of matter.
Properties that depend on the substances reaction with other substances?
Chemical properties depend on how a substance interacts with other substances, indicating its reactivity, stability, and ability to undergo chemical changes. These properties can include flammability, acidity, and corrosion resistance.
Explain the phrase like dissolves like and give an example of two like substances?
In chemistry, the term like dissolves like refers to the fact that similar type solutes will dissolve in solvents that have a similar type of chemical composition. Substances like water, acetone, and alcohol are polar molecules and so are soluble in each other. Substances that form non-polar molecules like oil and gasoline are soluble in each other. However, oil will not dissolve in water because of their different chemical bonds.
What is a common guideline for predicting solubility?
A common guideline for predicting solubility is "like dissolves like," which means that substances with similar polarities are more likely to dissolve in each other. For example, polar substances tend to dissolve in other polar substances, while nonpolar substances tend to dissolve in other nonpolar substances.
Is the ability to react with other substances a chemical properties?
Yes, the ability to react with other substances is considered a chemical property. Chemical properties describe how a substance interacts with other substances or undergoes chemical changes. This property helps to identify the behavior of a substance in chemical reactions.
Whats chemical composition?
Chemical composition refers to the arrangement, type and ratio of atoms in molecules of substances. Chemical composition varies when chemicals are added or subtracted from a substance, when the ratio of substances changes, or when other chemical changes occur in chemicals.
