During the day, the earth is heated up by the sun. The land gets hotter than the sea because it takes less energy to increase the land's temperature than to increase the sea's temperature. The land heats the air near it. This air rises and is replaced by cool air from the ocean, creating a "sea" breeze that blows from the ocean to the land during the day. Which forms of heat transfer are described above as helping to create a sea breeze? A. convection only B. radiation only C. convection and conduction D. conduction and radiation

C. convection and conduction

Explanation:

A sea breeze is a phenomenon that occurs during hot summer days when the sun transfers its heat to the earth surface by convection the land absorbs energy much easier than the seawater. As a result, the air above land will become warmer and as we know warmer air is lighter so this air will rise-up the air above the sea will now move from sea to the land to balance this air also there will be heat exchange between land air and the sea air by conduction and hence together they will create a phenomenon called a 'sea breeze'.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
