Question

the incomplete table below shows selected characteristics of gas laws.

\

$$\begin{tabular}{|c|c|c|c|} \\hline \\textbf{name} & \\textbf{variables} & \\textbf{constants} & \\textbf{equation} \\\\ \\hline ? & ? & ? & \\(p_1 v_1 = p_2 v_2\\) \\\\ \\hline charless law & ? & & \\(\\frac{v_1}{t_1} = \\frac{v_2}{t_2}\\) \\\\ \\hline ? & temperature, pressure & ? & \\(\\frac{p_1}{t_1} = \\frac{p_2}{t_2}\\) \\\\ \\hline combined gas law & pressure, temperature, volume & ? & ? \\\\ \\hline \\end{tabular}$$

which constants would most likely be filled in the first row of the table?

temperature and moles of gas
volume and temperature
pressure and volume
pressure and moles of gas

<reasoning>

Identify the gas law in the first row

\[
P_1V_1 = P_2V_2
\]

Determine the variables and constants

\[

$$\begin{aligned} &\text{Variables: } P \text{ (pressure), } V \text{ (volume)} \\ &\text{Constants: } T \text{ (temperature), } n \text{ (moles of gas)} \end{aligned}$$

\]

Match with the given options

\[
\text{Constants} = \text{temperature and moles of gas}
\]
</reasoning>

<mcq-correct>temperature and moles of gas</mcq-correct>
<mcq-option>volume and temperature</mcq-option>
<mcq-option>pressure and volume</mcq-option>
<mcq-option>pressure and moles of gas</mcq-option>
