Why is it important for a scientist studying greenhouse effect to know about mater,forces and energy
vova2212 [387]
<span>In the 19th century, scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet's temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century, Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed his idea as faulty. In 1938, G.S. Callendar argued that the level of carbon dioxide was climbing and raising global temperature, but most scientists found his arguments implausible. It was almost by chance that a few researchers in the 1950s discovered that global warming truly was possible. In the early 1960s, C.D. Keeling measured the level of carbon dioxide in the atmosphere: it was rising fast. Researchers began to take an interest, struggling to understand how the level of carbon dioxide had changed in the past, and how the level was influenced by chemical and biological forces. They found that the gas plays a crucial role in climate change, so that the rising level could gravely affect our future. (This essay covers only developments relating directly to carbon dioxide, with a separate essay for Other Greenhouse Gases. Theories are discussed in the essay on Simple Models of Climate.)</span>

How many atoms are there in 24 moles of Fe?
Semenov [28]

Answer: There are 145 \times 10^{23} atoms in 24 moles of Fe.

Explanation:

According to the mole concept, 1 mole of a substance contains 6.022 \times 10^{23} atoms.

Therefore, atoms present in 24 moles of Fe are calculated as follows.

24 mol \times 6.022 \times 10^{23} atoms/mol\\= 144.52 \times 10^{23} atoms\\or,  145 \times 10^{23} atoms

Thus, we can conclude that there are 145 \times 10^{23} atoms in 24 moles of Fe.

Why water is able to stick to the side of a glass
Snezhnost [94]

Answer:

Water uses adhesive forces that allow it to stick to certain surfaces such as glass.

Explanation:

When the angle between vertical direction and the glass wall is small, surface tension is stronger and the component of gravity perpendicular to the glass wall is small. The result of this causes water to stick to the side of a glass.

Hope this helps!
