Why do different substances have different odors?
Different substances have different odors because of their unique chemical compositions. When molecules from a substance enter the nose, they interact with olfactory receptors, which send signals to the brain that are interpreted as specific smells. The specific arrangement of atoms in a molecule determines its scent, leading to the wide variety of odors we perceive in different substances.
What is another name for chemial change?
Another name for a chemical change is a chemical reaction. It is a process where one or more substances are converted into different substances with unique chemical properties.
How do properties of new substances compare with properties of old substances?
The properties of new substances can vary depending on their chemical composition, structure, and interactions. They may have similarities to old substances, but can also exhibit unique characteristics due to different bonding arrangements or functional groups. Testing and analysis are typically required to determine how the properties of new substances compare to those of old substances.
How many different types of odors are there?
There is no definitive answer to this question, as the number of distinct odors that humans can detect is subjective and can vary depending on individual sensitivity and experience. However, it is estimated that humans can distinguish between thousands of different odors.
Does sodium have odor?
Sodium itself does not have a distinct odor. However, when sodium reacts with certain substances, it can produce compounds that may have odors.

Is odor a property of matter?
Yes, odor is a property of matter. It is caused by volatile molecules that are released from substances and detected by our smell receptors. Different substances release different molecules, resulting in the wide range of odors we can detect.
Why can you make millions of different substances from these different types of atoms?
The vast number of substances that can be formed from different types of atoms is due to variations in the arrangement and bonding of atoms. Atoms can combine in numerous ways to form different molecules with unique properties and structures, leading to a wide array of substances with varying properties and functions. This diversity allows for the creation of millions of different substances from a limited number of elements.

How does properties can be observed only when the substances in a sample of matter are changing into different substances?
Properties can be observed when a substance undergoes a chemical change, resulting in the formation of new substances with different properties. These properties can include changes in color, odor, temperature, and the formation of new substances. By observing these changes, we can identify and characterize the original substances based on their unique properties.
Is density unique to each substance?
Yes, density is unique to each substance. It is a physical property that is defined as the mass of a substance per unit volume. Different substances have different densities based on their molecular structure and composition.
How many different odors can the nose detect?
40,000.
Do compounds have different properties than the substances from which they are made?
Yes, compounds have different properties than the substances from which they are made. The properties of a compound are determined by the arrangement and interactions of its constituent atoms, leading to unique chemical and physical characteristics that are distinct from those of the individual elements.
Is baking brownies change or a chemical change?
chemical! new substances are being formed, heat is created, and odors are produced.
