Why are steam burns more serious than burns caused by an equal amount of equally hot water?
Why are steam burns more serious than burns caused by an equal amount of equally hot water? Steam is more likely to cause burn injuries than boiling water because of the latent heat of vaporization. Since water expands to approximately 1,600 times its volume when it turns from liquid to steam, steam often escapes its […]
What causes the attractive forces between particles in matter?
What causes the attractive forces between particles in matter? The particles that make up some matter are close together and vibrate back and forth. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together. What […]
What are the balls on powerlines?
What are the balls on powerlines? They’re called visibility marker balls or marker balls. You’ll often find them near mountain passes, in the deep valley areas, near major freeway crossings and around airports. They weight about 17 pounds each.

Can metaphors use as?
Can metaphors use as? This means that you cannot use the word “as” to establish a metaphor. When it establishes a comparison, that comparison is explicit. When it does not establish the comparison, that comparison may be implicit and therefore may be a metaphor. You can’t have metaphor and comparison at the same time. What […]

What is an example of an asthenosphere?
What is an example of an asthenosphere? The asthenosphere, in its capacity as a quasi-liquid, has convection currents that extend throughout its whole surface, under the entire area of the plates. The upper layer of asthenosphere under the South American plate, for example, is moving inexorably westward. What is the asthenosphere made of? The asthenosphere […]
