Are humans the smartest animal?
Are humans the smartest animal? Despite the prevailing belief that humans dominate the animal kingdom when it comes to smarts, we’re actually ranked as the third-smartest species on the planet — at least according to Douglas Adams, author of “Hitchhiker’s Guide to the Galaxy.” But joking aside, there is something to be said for Douglas’ […]
What element is a good insulator?
What element is a good insulator? Examples of good conductors are sliver, tin, and lead. Good insulators contain 8 electrons which mean they are stable(noble gasses group 18). Insulators can’t be easily transported from one atom to another and nonmetals make good insulators. Three examples of good insulators are sulfur, silicon, and rubber. What makes […]

What is the most powerful tugboat in the world? FUN FACT: While the 309.6t bollard pull of the ALP Striker is surely […]
What happens when entropy decreases?
What happens when entropy decreases? The total entropy of a system either increases or remains constant in any process; it never decreases. For example, heat transfer cannot occur spontaneously from cold to hot, because entropy would decrease. Entropy is very different from energy. Entropy is not conserved but increases in all real processes. What causes […]
Is the relationship between frequency and wavelength direct?
Is the relationship between frequency and wavelength direct? Wavelength (typically measured in nanometers) is the distance between two points in a wave. Frequency and wavelength have both direct and inverse relationships. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency. Is frequency and energy directly […]

What is the power of an appliance?
What is the power of an appliance? The power of an electrical appliance tells us how much electrical energy it transfers in a second. Power, P is measured in watts (W) where: 1 W = 1 J/s (joule/second). Appliances used for heating have a much higher rating than those used to produce light or sound. […]
