<em>Answer: The disasters are different according to their occurrence. For example, the causes of an earthquake cannot be the same as that of forest-fire. Natural disasters are caused due to different reasons like soil erosion, seismic activity, tectonic movements, air pressure, and ocean currents etc.</em>

Answer:
d. The number of moles
Explanation;
- According to the ideal gas;
P = nRT
where, P is the pressure, n is the number of moles, R is the ideal gas constant and T is the absolute temperature.
- Charles's law and Boyle's law revolve around, volume, temperature and pressure.
- According to Charles's law volume and temperature of a fixed mass of a gas are directly proportional at constant pressure.
- That is; V α T
- While based on Boyle's law, volume and pressure of a fixed mass of a gas are inversely proportional at constant temperature.
- That is, Pα 1/V
- We can, thus see that ideal gas law allows you to calculate number of moles unlike the case with Charles's and Boyle's law.
<span>(3) Atomic masses are a weighted average of the naturally occurring isotopes.

Here, we found this answer my looking at the key words 'naturally occurring isotopes'
An isotope is a different amount of neutrons, making the atomic mass change.

The dissolution of borax in water is a temperature dependent reaction. With the higher temperature, the salt dissolve quickly.
<h3>What is borax?</h3>
Borax is the hydrate salt of boric acid. It is white and widely used in cleaning and in laundry detergent.
Borax is a salt that will dissolve in water at almost any temperature, with the exception of steam and ice.
However, as with any salt, the higher the temperature, the faster the salt dissolves, so speed is dependent on temperature. It will dissolve in cold water, but it will take longer.
Thus, the dissolution of borax in water is a temperature dependent reaction.
