Answer:
Conduction directly affects air temperature only a few centimeters into the atmosphere. During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.
Explanation:
Answer:
1 ) H2O 2) Hydrogen and oxygen 3) Compound
Explanation:
1) To write a chemical formula, you write the number of molecules of an element (2 hydrogen atoms + 1 Oxygen atom, or H2O). The letters represent the element's notation on the periodic table, while the number that follows it represents the number of atoms of that particular element within the compound. If there is no number that follows the letter, there is only one.
2) Letter "H" on the periodic table represents hydrogen, while "O" represents oxygen
3) You can tell that this is a compound because it is made of two or more elements found on the periodic table

Molarity and normality are the ways of expressing concentration which includes the volume of the solution.
As we know,
Molarity is defined as the number of moles of solute dissolved in 1L of the solution. Thus,
M = no. of moles of solution/ Volume of solution on litres.
while, Normality is the number of gram equivalents of the solute dissolved per litre of the solution.
N = Gram equivalent of the solute/ volume of solution in litres.
while, the other concentration expressing terms such as mole fraction, molality includes the mass of the solution and solvent respectively.
