Step 1
: Understand the problem

We are asked to determine if KCl (potassium chloride) would be expected to be a solid at room temperature and provide a reason for our answer. To solve this problem, we need to know the melting point of KCl and compare it to room temperature.

Step 2
: Gather relevant information

The melting point of KCl is approximately 770.1°C or 1043.3 K (1). Room temperature is typically around 25°C or 298 K (2).

Final Answer

Yes, KCl would be expected to be a solid at room temperature because its melting point is significantly higher than room temperature. References: (1) "Potassium Chloride."
