Answer:
The new pressure is 44.4 kPa.
Explanation:
We have,
Initial volume, 
Initial pressure, 
It is required to find the new pressure when the volume is increased to 50 ml. The relationship between pressure and volume is known as Boyle's law.

is final pressure

So, new pressure is 44.4 kPa.
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.

Answer:
newtons 3rd law of motion
Explanation:
In dilution we add distilled water to decrease the concentration of required sample from high concentration to lower concentration
The law used for dilution:
M₁V₁]Before dilution = M₂V₂] After dilution
M₁ = 1.5 M
V₁ = ?
M₂ = 0.3 M
V₂ = 500 ml
1.5 * V₁ = 0.3 * 500 ml
so V₁ = 100 ml and it completed to 500 ml using 400 ml deionized water
