What is a characteristic of matter that can be observed or measured without changing the identity of the matter?
A characteristic of matter that can be observed or measured without changing its identity is its mass. Mass is a measure of the amount of matter in an object and can be determined through various methods, such as using a balance or scale, without altering the fundamental nature of the substance.
What electric charges are not observed in matter on the atomic scale?
Only integer multiples of the elementary charge (1.6 x 10^-19 coulombs) are observed in matter on the atomic scale. Non-integer or half-integer values of charge are not observed in nature.
Why is the wave nature of the matter not observed in daily life?
The wave nature of matter is not typically observed in daily life because the wave properties become more noticeable on a microscopic scale, such as with particles like electrons and atoms. In macroscopic objects, the wave behavior is negligible due to their larger size and interactions with other particles, causing their wave properties to be unnoticeable in everyday experiences.
What are the evidence of the particle nature of matter?
Some evidence of the particle nature of matter includes the discrete energy levels observed in atomic spectra, the photoelectric effect where light behaves like particles (photons), and the Compton effect where X-rays scatter off electrons in a way consistent with particle interactions. These phenomena suggest that matter can exhibit particle-like behavior.
What is the term for generalization about predictable ways in which matter and energy behave?
The generalization about predictable ways in which matter and energy behave is called a scientific law. Scientific laws describe observed phenomena and are based on repeated experimental observations.
What is a property of matter Than can only be observed by changing the basic nature?
what is a property of matter than can be measured or observed without changing the basic nature of the matter

Is property is a characteristic or feature of matter?
Property is a characteristic or feature of matter that can be observed or measured, such as size, shape, color, density, or temperature. These properties help define the nature and behavior of different substances.
What electric charges are not observed in matter on the atomic scale?
Only integer multiples of the elementary charge (1.6 x 10^-19 coulombs) are observed in matter on the atomic scale. Non-integer or half-integer values of charge are not observed in nature.
What is the difference between a chemical and a physical property of a substance?
A physical property can be observed without changing the material's composition. A chemical property can only be observed when a chemical change takes place.
Why is the wave nature of the matter not observed in daily life?
The wave nature of matter is not typically observed in daily life because the wave properties become more noticeable on a microscopic scale, such as with particles like electrons and atoms. In macroscopic objects, the wave behavior is negligible due to their larger size and interactions with other particles, causing their wave properties to be unnoticeable in everyday experiences.
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.
What uses familiar ideas to explain unfamiliar facts observed in nature?
A model uses familiar ideas to explain unfamiliar facts observed in nature.
What are three states in which matter is commomly?
The three states of matter are solid, liquid, and gas.
What state of matter is rare on earth?
Plasma is a rare state of matter on Earth. It is not commonly found in nature but can be observed in phenomena such as lightning and stars. Plasma is a state of matter in which atoms are stripped of their electrons, resulting in a highly electrically conductive gas.
What are the evidence of the particle nature of matter?
Some evidence of the particle nature of matter includes the discrete energy levels observed in atomic spectra, the photoelectric effect where light behaves like particles (photons), and the Compton effect where X-rays scatter off electrons in a way consistent with particle interactions.
