One kilojoule (kJ) is equal to 1,000 joules, making it a larger and more practical unit for measuring energy in many applications. This metric unit of energy, often seen on food labels in countries like Australia, quantifies the energy people get from consuming food and drink. To understand how much is 1 kJ of energy, we can translate it into relatable, everyday terms and comparisons.

Did you know a gallon of milk weighs approximately 2 ounces more than a gallon of water? Despite being composed of roughly 87% water, the presence of fats, proteins, and sugars means that milk does weigh differently than water, a fact rooted in the science of density.

According to one source, Quicksilver's body is so efficient that it metabolizes 95% of ingested food for energy, compared to a human's 25%. But to power his super-speed feats, how many calories does Quicksilver need to eat on a daily basis? The energy requirements vary drastically depending on whether we use comic book logic or real-world physics.

Formulas are foundational to nearly every scientific and mathematical field, with the Pythagorean theorem, $a^2 + b^2 = c^2$, being one of the most recognizable examples. They serve as a concise method for expressing relationships between variables, rules, and principles. This guide explores the diverse types of formulas used in different subjects, from basic algebra to complex chemical structures and data analysis.

Albert Einstein, the iconic physicist, was known for his groundbreaking theories, but his dietary habits were surprisingly simple and evolved over his lifetime. Far from a meticulous diet plan, his meals were often a matter of convenience and personal taste, though influenced by health issues later in life.

In physics, the mass-energy equivalence principle, $E=mc^2$, reveals that matter itself is the ultimate energy store. Understanding which substances store the most energy is crucial for everything from developing new fuels to advancing battery technology. While most people think of fossil fuels or batteries, the answer spans a far wider and more astonishing spectrum of materials.

While fat is known to provide more calories per gram than any other macronutrient, the question of what contains more energy per gram has a far more astonishing answer when moving beyond simple nutrition. It's a journey from the chemical bonds of everyday substances to the powerful forces within atomic nuclei.

While it's commonly assumed that 100 grams of liquid equals 100 milliliters, this is only true for pure water at a specific temperature. The actual volume of 100 grams of any other liquid is determined by its density, a physical property that measures mass per unit volume. This crucial difference means that for accurate measurements in cooking, science, and everyday life, you must account for the specific liquid you are using.

The term "siphon mode" refers to different functions depending on the context, from a boiler's automatic maintenance routine to a game mechanic where players drain health from opponents. This diversity in meaning makes it a phrase that requires clarification based on the specific field in which it is used.

A single can of soda contains several grams of dissolved carbon dioxide, a non-trivial amount of matter. But beyond the physical properties, does carbonation add weight in a way that impacts overall health?
