Did you know that ice cream is a complex colloid, not a single state of matter? The simple question, "Is ice cream a solid or not?" uncovers a surprisingly intricate intersection of chemistry and culinary art. This frozen treat is a fascinating blend of solid, liquid, and gas, all working together to create its signature creamy texture.

Did you know that an average glass of milk is comprised of almost 87% water, making the vast majority of its volume liquid? But calling milk "just a liquid" is an oversimplification, as the remaining portion is a mixture of fats, proteins, carbohydrates, and minerals suspended or dissolved within that liquid phase. Understanding what percent of milk is liquid involves appreciating its complex colloidal nature.

Though most people think of yogurt as a semi-solid food, it is scientifically characterized as a colloid, specifically a gel. This means yogurt is a complex mixture of solid particles dispersed within a liquid medium, a property that makes it both solid-like and liquid-like simultaneously.

According to food scientists, the act of cooking grains like oats causes their starch granules to swell and gelatinize, fundamentally altering their physical state. So, when asking 'Is porridge a fluid or milk?', the answer lies in understanding this key transformation and the resulting properties of the final dish.

Did you know that milk is approximately 87% water, yet is not a simple, homogeneous solution? The milk mixture is a complex colloidal system, comprised of essential fats, proteins, and sugars suspended within the water, making it a true wonder of natural chemistry.

According to airport security regulations, gels and spreads like jelly are subject to the same carry-on restrictions as liquids. But does jelly count as liquid in the scientific community? The answer is complex, revealing a fascinating overlap between food science, physics, and airport security, with the final classification depending on the context.

Milk, though appearing as a uniform, white liquid, is actually a complex substance with a fascinating scientific classification. The answer to **what mixture is milk classified as** is that it is primarily a colloidal dispersion, more specifically an emulsion, containing a mix of dispersed fat globules, protein micelles, and dissolved minerals.

According to the University of Washington Medical Center, gelatin (Jell-O) is explicitly listed as a food that should be counted toward a patient's total fluid intake on a restricted diet. This is because it is liquid at room temperature. For many, this definitive guidance answers the pressing question: Does Jell-O count as fluid?

According to the National Institutes of Health, bread is a solid, heterogeneous, and unstable foam. This initial definition, however, only scratches the surface of the complex physical state of a piece of bread, which challenges our basic understanding of solids, liquids, and gases.

Plain gelatin is often prescribed for clear liquid diets, like before a colonoscopy, because it's easy to digest and doesn't leave undigested residue. This medical context often clashes with gelatin's common solid form, sparking the question of its true nature.
