flows easily
That is a chemical property. A physical property could be its mass, volume, density, physical state, or that it can tear easily. A physical property is one that does not change the chemical composition of the substance.
An eruption is classified as explosive primarily based on the amount of silica (SiO2) found in the magma. Higher silica content increases the viscosity of the magma, preventing gas from escaping easily, which leads to the buildup of pressure and ultimately results in explosive eruptions. Conversely, magma with lower silica content tends to be less viscous and allows gases to escape more readily, resulting in less explosive activity.
Yes, the ability to melt easily is a physical property of a substance, not a chemical property. Chemical properties describe how a substance reacts with other substances or undergoes chemical changes.
If an eruption is quiet, it typically indicates that the magma has low viscosity due to high silica content. The high silica content causes the magma to be more fluid, allowing gases to escape easily and resulting in a gentle eruption with less explosive activity.
chemical
Oxidation is a chemical reaction, so it is a chemical property.
"Burns easily" is a physical property of a material because it describes how the substance reacts to a specific type of external stimuli (in this case, heat or fire). It is not an inherent part of the substance's chemical composition.
An effusive eruption typically produces less gas and is less viscous than an explosive eruption. Effusive eruptions involve the steady flow of lava, which is usually low in gas content and has a lower viscosity, allowing it to flow easily. In contrast, explosive eruptions are characterized by high gas content and high viscosity, leading to the violent expulsion of magma and ash. Therefore, effusive eruptions are generally less gaseous and less dense compared to explosive ones.
not easily compressed definite mass i think
physical. because you can easily change it back to water form and/or a gas.
