Define Standard Temperature and Pressure (STP)

\[

$$\begin{aligned} T_{\text{STP}} &= 0^\circ\text{C} \quad (273.15\text{ K})\\ P_{\text{STP}} &= 1\text{ atm} = 760\text{ mmHg} = 101.325\text{ kPa} \end{aligned}$$

\]

Match given options with STP values

\[

$$\begin{aligned} &\text{Option 1: } 30^\circ\text{C}, 100\text{ kPa} \quad (\text{Incorrect } T \text{ and } P)\\ &\text{Option 2: } -273.15^\circ\text{C}, 1\text{ atm} \quad (\text{Incorrect } T)\\ &\text{Option 3: } 0^\circ\text{C}, 760\text{ mmHg} \quad (\text{Correct } T \text{ and } P)\\ &\text{Option 4: } 25^\circ\text{C}, 101.325\text{ kPa} \quad (\text{Incorrect } T \text{ - this is SATP}) \end{aligned}$$
