Answer:
12.4 × 10∧3 atoms
Explanation:
Given data:
moles of oxygen molecule= 1.0000 x 10-20 mol
atoms =?
Solution:
32 g O2 = 1 mol = 6.02 × 10∧23
1.0000 x 10∧-20 mol × 6.02 × 10∧23 × 2 = 12.4 × 10∧3 atoms
Molarity is mole divided by volume in litres.
0.5mol divide by 0.5L = 1M
I think its density is 850kg/m^3
Answer:
Evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.
The evaporation and transpiration plays a major role in the water cycle as they help in formation of clouds and precipitation
Explanation:
Evaporation:
It is the process of formation and transfer of the water vapor from the surface of the liquid into the atmosphere.
Transpiration:
It is the process of transfer of the water vapors in the atmosphere from the pores present in the leaves of the plants.
The water is carried from the ground through the stems to the leaves.
The major difference between the evaporation and transpiration is that the evaporation happens from the any water body (like ponds, rivers, water stored in cup etc) while the transpiration essentially happens in plants only.
The evaporation and transpiration plays a major role in the water cycle as these process helps in transfer of the surface water into the atmosphere, which helps in formation of clouds and precipitation.
