Why jet streams have such a high velocity?
Why jet streams have such a high velocity? Temperature also influences the velocity of the jet stream. The greater the difference in air temperature, the faster the jet stream, which can reach speeds of up to 250 mph (402 kph) or greater, but average about 110 mph (177 kph). Can the jet stream reverse? Now, […]

Does sugar dissolve faster in hot or cold water?
Does sugar dissolve faster in hot or cold water? Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, […]
What is the relation between power and frequency?
What is the relation between power and frequency? The relationship between power and frequency is inversely proportional to each other . The power demand reduces in the load so that the frequency increases in the transient period but at steady state condition. Frequency is number of waves that pass a fixed place in a given […]

Who predicted properties of undiscovered elements? Mendeleev What are elements that have some properties of metals and some properties of nonmetals called? Metalloids may act either like metals or nonmetals in chemical reactions. Most metalloids have some physical properties of metals and some physical properties of nonmetals. They fall between metals and nonmetals in their […]
How do you ensure accuracy in a titration?
How do you ensure accuracy in a titration? Terms in this set (9) Meniscus at eye level. To avoid parallax error. White tile. To see end point clearer. Remove funnel before titrating. Increases the vol making the titre smaller. Dropwise addition. No bubbles in pipette & burette at the tip. Swirling during titration. Few drops […]
How do you classify a metal?
How do you classify a metal? The elements can be classified as metals, nonmetals, or metalloids. Metals are good conductors of heat and electricity, and are malleable (they can be hammered into sheets) and ductile (they can be drawn into wire). Is Silicon harmful to humans? Silicon crystalline irritates the skin and eyes on contact. […]
