What are some good insulators? Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of […]

Does the amount of solvent change when you dilute a solution? 1. Learn how to dilute and concentrate solutions. Often, a worker will need to change the concentration of a solution by changing the amount of solvent. Dilution is the addition of solvent, which decreases the concentration of the solute in the solution. What is […]

What comes through nuclear pores? Each nuclear pore is a large complex of proteins that allows small molecules and ions to freely pass, or diffuse, into or out of the nucleus. Similarly, RNA transcribed in the nucleus and proteins that are destined to enter the cytoplasm have nuclear export sequences that tag them for release […]

What are the main components of a map? There are three Components of Maps – distance, direction and symbol. Maps are drawings, which reduce the entire world or a part of it to fit on a sheet of paper. Or we can say maps are drawn to reduced scales. But this reduction is done very […]

How hot is too hot for winter tires? All-season tires begin to lose their grip once temperatures drop below +7C and are nearly useless for any temperature below -10C. Is 60 degrees too warm for winter tires? They are usually fine as long as temps don’t go too far above 60. It’s better to run […]

How can I tell if my glass is heat-resistant? If it is a heat-resistant glass, there will generally be a corresponding label on the glass, indicating the temperature and range of use; If you find nominal Pyrex glass at a low price, consider its authenticity. Is all glass heat-resistant? Glass is thermal-shock resistant, meaning it […]

What is the maximum number of water skiers that may be towed legally behind a vessel in NH? How many people can be towed behind a vessel at one time? No more than six people may be towed on one or more inflatable tubes and no more than two people may be towed on water […]

How far away can the siren be heard? The physics of sound will reduce the volume of the siren as the distance from the siren increases. With today’s modern vehicles, the effective range of the siren at a 90-degree intersection is often no more than 80 feet. Does pitch change with distance? Sound waves that […]
