What is a physical combination of two or more substances that does not make a new substance?
A physical combination of two or more substances that does not create a new substance is known as a mixture. In a mixture, the individual components retain their original properties and can typically be separated by physical means, such as filtration or distillation. Examples include salad, air, and sand and salt combined together. Unlike a chemical compound, the substances in a mixture do not undergo a chemical reaction.

Why is mixture not a substance?
A mixture is not a substance because it is made up of two or more different substances that are physically combined together but can be separated by physical means, such as filtering or evaporation. Substances, on the other hand, are pure and cannot be separated by physical means.
Is it a physical change or a chemical change when substances combine to make new substances with new properties?
Chemical change.
What causes substance to combine in different ways to make other substance?
Substances combine through chemical reactions when their atoms rearrange to form new molecules with different properties. This occurs when atoms bond to each other to achieve a more stable configuration, which can involve sharing electrons or transferring them between atoms. The resulting substances may have distinct physical and chemical properties compared to the original substances.
What makes substances different from each other?
its physical and chemical properties. The temporal force is the dominant force which evolves flowing from the present to the future causing variations in the shape and speed of the sequence of change of substances!
What distinguishes a mixture form an impure substance?
If a substance in a mixture is preponderant--, if the amount far exceeds the amounts of the other substances in the mixture it is usually called an impure substance. Resource: Separation of the Components of a Mixture Lab -Chemistry
Can you make a sentence with mixture and physical change?
A mixture is a mix of substances such as blood or juice, physical changes only alter the form of the object not the substance itself.
How you differentiate substance from mixtures?
Substances are pure and consist of only one type of material with definite chemical properties, while mixtures are composed of two or more substances physically combined. Mixtures can be separated using physical methods, whereas substances cannot be broken down further by physical means.
Why is mixture not a substance?
A mixture is not a substance because it is made up of two or more different substances that are physically combined together but can be separated by physical means, such as filtering or evaporation. Substances, on the other hand, are pure and cannot be separated by physical means.
When a substance undergoes a physical change what does not a change?
The chemical make up of a substance does not change. It must remain the same combination of atoms or molecules to be considered only a physical change.
What is a difference between a substance and a material?

What is called a change that does not make a substance into a new substance?
A change that does not make a substance into a new substance is called a physical change. In physical changes, the physical properties of the substance may change, such as shape, size, or state (solid, liquid, gas), but the chemical composition remains the same.
What is the substance used in chemistry?
Substances are used to make chemical reactions.
Is combining hydrogen and oxygen to make water is a physical?
No.
The different of mixture and substance?
The difference between a pure substance and a mixture is that a pure substance, such as aluminum, has one type of particle in it and mixture, such as salt, has two or more particles within it or two pure substances.
Does a physical change make the substance that undergoes it a different substance if not then what can change?
After a physical change a substance does not change its chemical composition it simply changes its state as, water to ice or vapours.
What substances make sheetrock?
Gypsum or 'calcium sulfate dihydrate' is the only substance used.
What is a physically combined pure substance?
Pure substances that are physically combined make a mixture.
