What does subtance mean?
Substance is the correct spelling. It is the real and physical matter that a thing or person consists of and that has a solid and tangible presence. It is a particular type of matter that has uniform properties.
Why can you use the melting point to help identify a material?
The melting point is a characteristic physical property of a substance, and it can be used to help identify a material because each pure substance has a specific melting point under standard atmospheric conditions. By comparing the measured melting point of an unknown sample to known melting points of potential materials, you can narrow down the possibilities and identify the substance. Additionally, impurities can cause variations in melting point, so a sharp melting point indicates higher purity, further aiding in identification.
What is the time it takes for half of a raioactive substance to decay?
The time it takes for half of a radioactive substance to decay is known as the half-life of the substance. It is a fixed characteristic of a particular radioactive material and varies depending on the specific isotope.
What are the usefulness of density in identification of unknown substance?
Density is useful for identifying an unknown material because it is a physical constant. A physical constant is a unique characteristic of the material in question. This constant never change or vary with the shape or amount of the material/substance.
What is the other name of a substance?
Another name for a substance is a material.
How do you identify the criteria that determines a substance as being a hazardous material?
identify the criteria that determines a substance as being a hazardous material
What are the benefits of using a liquid absorbing material in cleaning up spills?
Using a liquid absorbing material to clean up spills has several benefits. It helps to quickly and effectively soak up the liquid, preventing it from spreading and causing further damage. This material also makes it easier to remove the spilled substance, reducing the risk of slips and falls. Additionally, using a liquid absorbing material can help to minimize the environmental impact of the spill by containing and absorbing the liquid before it can seep into the ground or waterways.
Is glass wool a sound absorbing material or not?
yes.glass wool is one of the sound absorbing material while ground glass is not.
What is the specific gravity for Pretoria?
Specific gravity is a measure of the density of a substance compared to the density of water. For a location like Pretoria, specific gravity would typically refer to the density of a particular material or substance found there, rather than the location itself. If you are referring to the specific gravity of a particular material in Pretoria, please specify the material for a more accurate answer.
What does subtance mean?

Why are mass and volume not characteristic properties but the density of a material is?
Mass and volume can vary depending on the size or amount of a substance, while density remains constant for a specific material. Density is a characteristic property because it is unique to each substance and helps identify the substance regardless of its mass or volume.
What is material frequency?
Material frequency refers to how often a particular material or substance is used or encountered in a given context, such as in a specific industry, product design, or research material. It is used to determine the prevalence and importance of a material in a certain field.
The amount of material in a substance?
The amount of material in a substance is mass.
Is glass wool a sound absorbing material?
Yes

What does it mean to identify a property of a material?
To identify the property of a material means to identify the characteristics of a material. example: The fabric was light and slightly transparent.
What is the best material for absorbing water efficiently?
The best material for absorbing water efficiently is hydrogel, a superabsorbent polymer that can hold a large amount of water relative to its own weight.
