What does the zeroth law of thermodynamics allow us to define?
2 answers:
Explanation:
Zeroth law of thermodynamics states that when two thermodynamic systems are in equilibrium with a third system then all of them are in thermal equilibrium with each other.
For example, system A is in thermal equilibrium with system B and system B is in thermal equilibrium with system C then it means system A is also in thermal equilibrium with system C.

<h3>Further explanation </h3>Titration is a procedure for determining the concentration of a solution (analyte) by reacting with another solution whose known concentration (usually a standard solution) is called the titrant. Determination of the endpoint/equivalence point of the reaction can use indicators according to the appropriate pH range
Titrations can be acid-base titration, depositional titration, and redox titration. An acid-base titration is the principle of neutralization of acids and bases
Reaction
HNO₃ + NaOH → NaNO₃ + H₂O
Concentration a standard solution of sodium hydroxide : 0.0998 mol/dm³ , and the volume = 25 cm³
moles NaOH=
<em>From the equation, mol ratio HNO₃ : NaOH = 1 : 1, so mol HNO₃ = mol NaOH=</em><em>2.495 mlmoles</em>
<em></em>
The volume of HNO₃ = 21.8 cm³, so the concentration :
