What is the difference between rising and sinking air?

What is the difference between rising and sinking air? Rising air always cools, and, conversely, sinking air always warms. This type of temperature change, which is caused simply by ascent or descent in the atmosphere, is called adiabatic cooling or warming. When air moves vertically, its pressure changes. What is the diff between climate and […]

Which solid has the highest melting point?

Which solid has the highest melting point? tungsten Do impurities lower melting point? The presence of even a small amount of impurity will lower a compound’s melting point by a few degrees and broaden the melting point temperature range. Because the impurity causes defects in the crystalline lattice, it is easier to overcome the intermolecular […]

Is any closed conducting path?

Is any closed conducting path? There must be a closed conducting loop from the positive to the negative terminal in order to establish a circuit and to have a current. When this occurs, the circuit is opened and a closed conducting loop no longer exists. Without a closed conducting loop, there can be no circuit, […]

Who is the father of atom?

Who is the father of atom? Basic Atomic Structure. The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the “father” of atomic theory, but judging from this photo on the right “grandfather” might be a better term. How thick […]

When was E mc2 proven?

When was E mc2 proven? 1905 Does the inertia of a body depend on its energy content? The mass of a body is a measure of its energy-content; if the energy changes by L, the mass changes in the same sepse by L/9 10%, the energy being measured in ergs, and the mass in grammes. […]

Will the price of silver go up in 2020?

What is stream function and velocity potential?

What is stream function and velocity potential? Introduction. The stream function, ,, is a function specially suited for dealing with two- dimensional flow while the velocity potential, f, is a function which may be. used with either two- or three-dimensional flow. What is unit for flow rate for gases? Because of this, meter flow rates […]
