What element transmits heat easily

Hurricanes are intense storms that originate in the Tropics. Hurricanes begin life as a small gathering of unorganized storms which gain energy from the heat of the ocean water. If certain conditions in the atmosphere are present, the gathering of individual clouds will begin to organize into a single storm. If the storm continues to feed off the heat supplied by the ocean, the organization of the cloud clusters will intensify and the winds will increase and circulate around a specific center, the eye. As a matter of fact, meteorologists place hurricanes in a category called cyclones. Cyclones are characterized by a circular wind pattern or circulation. Tornadoes, waterspouts, and dust devils are also members of this category.

During a hurricane, the air pressure decreases. This is the most important characteristic of a hurricane. Now do you think you know when Bertha passed? On July 11, near hour 14. It is at this time that the air pressure was at a minimum. Also, the wind speeds increase when a hurricane approaches. At hour 14, the wind speed and wind gust are near their maximum values of 18 meters/second and 24 meters/second, respectively. Keep in mind that Station 41010 was not near the most dangerous and intense area of the hurricane -- the eye wall. If this station were nearer the eye wall, the wind speeds and gusts would have been much higher and the air pressure would have been much lower.

A sealed vessel containg helium, chlorine and fluorine has a total pressure of 205 kpa and partial pressures of 15 kpa for chlor

MrRa [10]

According to Dalton's law of partial pressure

The total pressure of a mixture of ideal gases is sum of the partial pressures of each gas present in the mixture

So if we know the partial pressure of all the gases we can determine the total pressure of the mxiture by adding all of them.

Thus

Ptotal = PCl2 + PF2 + PHe

Thus

Partial pressure of helium = 205 - ( 89 + 15) = 101 kPa

Which of the following sample will have the greatest average speed at 355 K?. A. CH4. B. Ne. C. C2H4. D. Cl2

Amanda [17]

Answer:

The correct option is methane : $CH_4$ .

Explanation:

Average speed of the gas molecules id given by expression:

$v_{avg}=\sqrt{\frac{8kT}{\pi m}}$

k = Boltzmann cosnatnt

T = Temperature of the gas molecules = 355 K

m = molecular mass of the molecule

$v_{avg}\propto \sqrt{\frac{1}{m}}$

Molar mass of methane = 18 g/mol

Molar mass of neon = 20.18 g/mol

Molar mass of ethene = 28 g/mol

Molar mass of chlorine gas = 70 g/mol

Lower the value of molar mass of gas molecule higher will be the average speed.So, from the given options methane gas greatest average seed because it has lowest molecular mass
