What else can I help you with?
Which of the following processes does not involve a chemical change in property A rusting B boiling C burning D fermenting?
Boiling does not involve a chemical change in property. Boiling is a physical change in which a substance changes from a liquid to a gas without changing its chemical composition. The other options (rusting, burning, fermenting) involve chemical reactions that result in changes to the chemical composition of the substances involved.
Are boiling points and freezing points examples of chemical properties?
No, boiling points and freezing points are examples of physical properties, not chemical properties. Chemical properties describe how a substance interacts with other substances to form new substances, while physical properties describe characteristics that can be observed without changing the chemical composition of the substance.
What is a not a example of a physical properties?
Personality traits, emotions, and thoughts are not examples of physical properties. Physical properties are characteristics of a substance that can be observed or measured without changing the composition of the substance, such as color, density, or boiling point.
Is reacts with acid to form H2 a chemical or physical properties?
This is a chemical property, as it involves a chemical reaction where hydrogen gas is produced when the substance reacts with an acid. Physical properties refer to characteristics such as color, state, density, and boiling point.
Is something that boils at 20 degrees C chemical or physical?
Boiling at 20 degrees Celsius is a physical property. Chemical properties involve changes in the chemical composition of a substance, while physical properties describe the state or appearance of a substance without changing its composition.
What physical properties are intensive?
The three intensive physical properties are density, boiling point and melting point.
Are melting and boiling point physical properties of a substance?
Yes, melting and boiling points are physical properties of a substance. They represent specific temperatures at which a substance transitions from one phase to another - solid to liquid for melting point, and liquid to gas for boiling point.
What part of fractional distillation is physical?
The separation of components in fractional distillation is a physical process because it involves differences in physical properties such as boiling points to separate the components. In fractional distillation, the mixture is heated to vaporize the components, which are then cooled and condensed based on their differing boiling points.
Which of the following processes does not involve a chemical change in property A rusting B boiling C burning D fermenting?
Boiling does not involve a chemical change in property. Boiling is a physical change in which a substance changes from a liquid to a gas without changing its chemical composition. The other options (rusting, burning, fermenting) involve chemical reactions that result in changes to the chemical composition of the substances involved.
What are two physical properties of metal?
Density Boiling point
Is a boiling point a chemical property of a sustance?
No, boiling points and freezing points are physical properties.
What are 3 intensive physical properties?
Density, melting point, and boiling point are three examples of intensive physical properties. These properties do not depend on the amount of substance present and are useful for identifying and characterizing materials.
Are boiling points and freezing points examples of chemical properties?
No, boiling points and freezing points are examples of physical properties, not chemical properties. Chemical properties describe how a substance interacts with other substances to form new substances, while physical properties describe characteristics that can be observed without changing the chemical composition of the substance.
What distinguishes mead from beer in terms of ingredients and production processes?
Mead is made from honey, water, and yeast, while beer is made from malted barley, water, hops, and yeast. The production process for mead involves fermenting honey and water, while beer involves mashing barley, boiling with hops, and fermenting.
Physical change involves change in?
physical change involves viscosity, conductivity, melting point, boiling point, density, malleability and hardness.
Color odor boiling points melting points are all examples of what properties physical or chemical?
Physical
How can you tell that melting boiling dissolving are physical changes?
The physical and chemical properties, and chemical composition, are not changed after a physical change.
