Which characteristic of water protects fish when a lake freezes? \\ A. cohesion B. All of the these characteristics. C. water as a solvent D. water is less dense as a solid If the evaporation rate of the global ocean is 1 meter each year and the average depth of the oceans is about...
Specific gravity is used is determine the ratio of the density of one material to the density of another standard material. A number greater than 1 means that it is more dense than the reference while a number of less than 1 means that it is less dense. ...
2. Choose a name that is easy to remember but not too common. This prevents confusion when multiple networks have similar names. 3. Incorporate numbers or special characters if your router supports them. This makes the name unique and less likely to clash with nearby networks. 4. Avoid using...
Gases have a very low density because their particles are very far apart; for example, air has a density of 0.0013 g/cm3.The Floating Test If an object is more dense than water, it sinks, but if it is less dense than water, it floats. For example, in an oil spill in the ocean,...

heating up the surrounding air. Expansion occurs in the less dense warm air and an area over the land having low pressure is developed. At the same time on the top of the sea, a high-pressure area develops. Due to the difference in pressure, the air flows from the high pressure over ...
STP is one atmosphere of pressure at 0 degrees C. Since this would be a freezing temperature at sea level, dry air is less dense than the cited value most of the time. However, air typically contains a lot of water vapor, which would make it denser than the cited value. ...
An increase or decrease in the density of a chemical substance in an area is called?Why is ice less dense than water? What is the formula for density?What is the pH of seawater?Sponges are found ___. a. only in seawater. b. mostly in freshwater. c. only in freshwater. d. mostly...
