During El Niño, changes in wind and ocean current patterns result in warm waters stretching across the whole Pacific Ocean. This extra heating causes changes in wind patterns, which causes atmosphere to react and change all the way from the ground to the edge of space around Earth.

Answer:
12.044 × 10²³ atoms of oxygen
Explanation:
Given data:
Number of atoms of oxygen = ?
Moles of oxygen = 2 mol
Solution:
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms of oxygen
2 mole × 6.022 × 10²³ atoms of oxygen / 1 mole
12.044 × 10²³ atoms of oxygen
Advantages of alloys:
-high strength-to-weight ratios
-a wide range of different alloys, to suit a range of different uses
-low density
Disadvantages of alloys:
-No fatigue limit
-prone to corrosion, so need protective finishes, particularly magnesium alloys
-Many alloys have limited strength, especially at elevated temperatures magnesium alloys have low strength
Radiation, because heat travels in all directions Convection, and heat travels in all directions Conduction, and it also heat travels from hot to cold Radiation, because heat travels from cold to hot.
