Coca-Cola is a ubiquitous beverage, but how much does 1 liter of Coca-Cola weigh? Answering this question reveals a basic principle of chemistry, as the mass of the liquid is slightly greater than a liter of pure water due to its dissolved sugars.

A gram is a unit of mass, while a milliliter is a unit of volume, fundamentally representing two different physical properties of matter. So, are ml and g the same on a scale? The answer is no, with the famous exception of pure water, where 1 milliliter and 1 gram are approximately equal.

Water expands by approximately 9% when it transitions into a solid state. Therefore, **what is 100g of ice** physically represents a volume greater than 100g of liquid water, a unique property critical in nature and engineering.

Did you know that while all liquids are considered fluids, the reverse is not always true? The question, is milk a liquid or fluid, reveals fascinating insights into the unique physical and chemical makeup of this common beverage and the precise definitions used in science.

In chemistry and everyday life, the phenomenon of dilution is a fundamental concept. When you add more water to a strong cup of coffee, for example, the reason you decrease concentration is because you are increasing the total volume while the amount of coffee grounds remains the same. This simple principle is governed by the laws of concentration and dilution.
