Answer:
See explanation
Explanation:
According to Avogadro's law, the volume of a given mass of gas is directly proportional to the number of molecules of gas present at constant temperature and pressure.
Hence; V1/n1 = V2/n2
The implication of this is, if there were X molecules present and the volume of the balloon is halved, the number of molecules of gas present is also halved. So, we now have X/2 number of gas molecules present in the balloon.
This is in accordance with the statement of Avogadro's law.
True that in the preindustrial era, settlements were more likely to be near sources of surface water than in the industrial era. The main reason being that during the preindustrial era people were dependent mostly on irrigation. For irrigation people were dependent on surface water. This was the main and basic reason.
Combination of biology and materials
This branch of science is called as Bio materials
This disciple covers the science and function of all equipment that is used in the biology
Ionic compunds are able to conduct electricity when molten/in solution, but not when they are solid
- By changing three atom bond angle , we can change molecular polarity. if bond angle is 120° and all atom has same electronegativity, the resultant polarity ( dipole moment ) become zero. we can change bond anngle either less than or greater than 120°, but not exactly 120
- Replacing one or more atom with different atoms having electro negativity values also make molecular poles.
- By placing molecules under external electric field or magnetic field also causes to the molecule.
