Gases, fluids, and
other solids in contact with a moving object will produce heat due to friction.
The contact between molecules or atoms present in gases, fluids, and other
solids creates energy and it may be in the form of heat.
It is an proportional relationship
Pressure increases so does temperature and vice versa
Answer:
10
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
Thus, from the formula, more the concentration of the hydrogen ions or more the acidic the solution is, the less is the pH value of the solution.
Thus, solution with pH = 3 will be more acidic than solution with pH =4
Thus, concentration of the [H⁺] when pH =3
3 = - log [H⁺]
[H⁺] = 10⁻³ M
For pH = 4, [H⁺] = 10⁻⁴ M
<u>hence, pH = 3 is 10 times more acidic than pH = 4</u>
salt which is soluble in water and
is converted to
which is also soluble in water
