Why are moles and volume directly proportional? Avogadro’s law states that “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules.” For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant. What […]

Why are all bubbles round?
Why are all bubbles round? Bubbles are round because there is equal pressure all around the outside of the bubble. The perfectly round shape that most bubbles have is called a sphere. Are bubbles always circular? Scientists refer to bubbles as “minimal surface structures.” This means that they always hold the gas or liquid inside […]
How do you randomly select participants?
How do you randomly select participants? Simple random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected. Data is then collected from as large a percentage as possible of this random subset. […]

What materials have the most friction?
What materials have the most friction? A typical high friction material is rubber, which is used in a variety of applications such as shoes and tires. The adhesive system of gecko lizards also demonstrates high friction. Unlike other high friction materials, the gecko’s adhesive is composed of rigid, durable material. How does oil affect friction? […]

Is it possible to have your entire genome mapped?
Is it possible to have your entire genome mapped? Whole genome sequencing is available to anyone. Although the technical conditions, the time and the cost of sequencing genomes were reduced by a factor of 1 million in less than 10 years, the revolution lags behind. Before you start worrying, I can assure you: it will […]
