Which property properties contributes to the high surface tension of water?
Which property properties contributes to the high surface tension of water? Water has cohesive and adhesive properties. Cohesive forces are responsible for surface tension, the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water also has adhesive properties that allow it to stick to substances other than itself. Which […]

Do astronomers use reflecting or refracting telescopes?
Do astronomers use reflecting or refracting telescopes? A refractor uses lenses within a tube to refract (bend) light. It’s the type of long telescope which you might imagine old-time astronomers, like Galileo, using. Reflectors, on the other hand, use mirrors instead of lenses to reflect light. Most modern observatories use reflectors because their telescopes are […]
