In a phase diagram, the point at which the solid, liquid, and gas coexist simultaneously is called the TRIPLE POINT. There is a specified pressure and temperature at which the substance can exist in equilibrium with these three phases being present.

Answer:

Triple point.

Explanation:

The point in the phase diagram where all the three phases (solid, liquid and gas) exist together is known as triple point.

At triple point:

C= components = 1

P = phase = 3

Therefore degree of freedom will be:

F = C-P+2 = 1-3+2=0

Thus the degree of freedom is zero.

For example:

The triple point of water is at 0.0075 degree celsius and 4.58 mmHg pressure.

Compare and contrast global winds and local winds

Local winds blow over certain parts of the Earth, but global winds blow around the globe as the name 'global' suggests.

Local winds like the Sirocco, Harmattan, leveche, Nor'westers, Mistral, Chinook, Foehn can be found only in certain regions. For example, Sirocco, Harmattan, are seasonal winds blowing across Northern Africa and the Leveche blows over Southern Spain. The Chinook are warm winds flowing down the leeward side of the Rocky Mountains. The Mistral is a chilly wind which blow in the Mediterranean regions during winter.

The Trade winds, Mid Latitude Westerlies and Polar Easterlies are examples of global winds.

The Trade Winds are found between the 30 degrees S and N latitudes. There are the North-East Trades and the South-East Trades, both converging at the the Equator.

The Westerlies are a deep wind system found in the Temperate latitudes blowing from the West towards the East.

The Polar Easterlies blow from the Polar regions towards the Mid-latitudes.

A chemist determines by measurements that 0.0200 moles of chlorine gas participate in a chemical reaction. Calculate the mass of

Schach [20]

Answer:

1.4200 g

Explanation:

The chlorine gas has a molecular formula Cl2. In table periodic, the molar mass of one atom of chlorine is 35.5 g/mol, so the molar mass of Cl2 is 71 g/mol.

Molar mass, mass and number of moles are related by the equation below:

$n = \frac{m}{MM}$
