Nitrogen. Oxygen. Carbon Dioxide. Carbon Monoxide. Water Vapour. Helium. Neon. What are the common gases? Common gases include Acetylene, Argon, Carbon Dioxide, Helium, […]

What is the relationship of kinetic and potential energy? The primary relationship between the two is their ability to transform into each other. In other words, potential energy transforms into kinetic energy, and kinetic energy converts into potential energy, and then back again. At what position does the ball have the greatest potential energy? The […]

Can you run jet fuel in a diesel? Jet fuel (there’s variants, but a very common one is known as Jet A) is really close to regular old diesel fuel. And, for that matter, kerosene. You can even run it straight in your diesel car or truck, though it doesn’t lubricate as well so if […]

What is the thinnest liquid? Thanks to the “super material” graphene, a team of researchers managed to create one of the world’s thinnest layers of liquid. There’s now a new understanding of the word “wet” thanks to physicists who created the thinnest film of liquid ever. What is a viscous sauce? A sauce that runs […]

What is the total volume of the world? Total surface area of Earth is 510,082,000 sq. km. The oceans cover ~70.9%….Table 1. Volumes of the World’s Oceans from ETOPO1. Download Table 1 as a . PDF. North Atlantic Volume (km3) 146,000,000 % Ocean Volume 10.9 Avg. Depth (m) 3519 Max Depth (m) 8486 What percent […]

Is it a look or take Alook? The difference between “have a look” and “take a look” is geographical rather than semantic. The former phrase is usually used in the UK, whereas the latter is usually used in the USA. Is have a look formal? Both of the sentences that you suggested are grammatically correct, […]

How do you know if a sample is representative? A representative sample should be an unbiased reflection of what the population is like. There are many ways to evaluate representativeness—gender, age, socioeconomic status, profession, education, chronic illness, even personality or pet ownership. What percentage of sample is representative? For example, in a population of 1,000 […]

Do neurons allow us to think? In short, our nervous systems detect what is going on around us and inside of us; they decide how we should act, alter the state of internal organs (heart rate changes, for instance), and allows us to think about and remember what is going on. To do this, it […]

Why is light important for humans? Earth has been bathed with light from the Sun ever since; it is our most important source of energy. Sunlight warms us, causes weather patterns, allows plants to manufacture oxygen and our food from carbon dioxide and water, and it allows us to find our way around in the […]

What are the factors affecting the solubility? Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of […]
