Is CRT TV bad for eyes? There are two things about CRTs that can potentially damage eyesight. #1 is staring at the same close-range object for hours at a time, causing eyestrain. The muscles that focus the lens are forced to hold one position for a long time, and that can hurt them after too […]

Why are heat islands dangerous? Heat islands contribute to higher daytime temperatures, reduced nighttime cooling, and higher air-pollution levels. These, in turn, contribute to heat-related deaths and heat-related illnesses such as general discomfort, respiratory difficulties, heat cramps, heat exhaustion, and non-fatal heat stroke. What causes a heat island? How Do Heat Islands Form? Tall buildings […]

What time of day do most people do laundry? When is the best time to wash clothes? Try washing before 4 p.m. or after 7 p.m. – Many energy companies charge extra for electricity during their “peak hours,” which see increased energy usage.

Is Air a better conductor or insulator? Air is a collection of gases, and it is not a good conductor or radiator. Air is excellent at convection, but the amount of heat that can be transferred is minimal because the low mass of the substance cannot store a great deal of heat. Air is used […]

Which is stronger cobalt or nickel? It was found that cobalt was even stronger than nickel, possess- ing a tensile strength of about 65,000 pounds per square inch. What do iron nickel and cobalt have in common? A magnetic alloy is a combination of various metals from the periodic table such as ferrite that contains […]

Conductivity : A poor conductor of heat and electricity. Solubility : Slightly soluble in water, alcohol and some other common liquids. Density : […]

How is science used in basketball? Basketballs bounce because of the pressurized air inside of them, gravity and Newton’s Laws of Motion. When you dribble a basketball, your hand and gravity both push the ball towards the ground (Law #1). The energy in the compressed air is transferred back to the ball pushing it back […]
