Properties of Jello: Solid, Liquid, or Gas?

Jello and Its Properties

• Jello is classified as a mixture due to its physical composition, using ingredients that do not chemically combine.
• The primary components of jello are boiled water and gelatin mix, requiring only these two ingredients for preparation.
• Freezing jello is possible, but the process is time-consuming.

Mixing and Solubility

• Adding excessive water to the gelatin mix can prevent complete dissolution of the mixture.
• Alternative liquids, such as milk, can be used instead of water to create jello.

States of Matter

• Solids have tightly packed atoms that do not allow movement, making them rigid and unyielding.
• Liquids take the shape of their container with atoms that are close but not rigidly compact.
• Gases consist of atoms that are spaced far apart, allowing them to move rapidly in all directions.

Definitions Relevant to Matter

• Matter is defined as any physical substance with mass that occupies space.
• A chemical reaction involves two different substances combining to form a new substance.
• A physical change is a process used to separate different components within mixtures.

Key Properties of Matter

• Density refers to the compactness of a substance, measured as mass per unit volume.
• Flammability describes a substance's capability to ignite or burn.
• Malleability is the ability of a material to be shaped without breaking.
• Solubility pertains to the property of a substance to dissolve in a solvent.
• Viscosity indicates the thickness and stickiness of a fluid, affecting its flow.
• A colloid is a mixture with microscopic particles evenly dispersed, creating a uniform appearance.

Other Concepts

• Rust forms on metals like iron due to oxidation in the presence of moisture, highlighting a chemical change.
• Odor refers to a distinctive smell that can be characteristic of certain substances.
• The principle of conservation of matter asserts that mass remains constant in a closed system without external forces.
• Function refers to the inherent activity or purpose designed for an object or substance.
• Properties of matter encompass various characteristics, including mass and volume measurement.
