Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.
The most appropriate answer is C !!
I remember this from a week ago. The answer was topex/poseidon
<span>Good Morning!
To measure the volume of an acid we use in the laboratory an instrument called burette (a). This instrument is used to calculate the volumes of chemical solutions. At first glance, these tools may be confused with syringes, but have different functions.

Question 1:
(a) Sulfurous acid: H2SO3
Sulfuric acid: H2SO4
(b) Nitrous acid: H2NO2
Nitric acid: H2NO3
Question 2:
To calculate the pH, based on concentration of H+ ions, there is one formula:
So the pH of this solution is
(the solution is basic).
