Answer:
116 °C
Explanation:
The given parameters of the Substance Q are;
The boiling point of Q = 445°
The substance Q is a solid at room temperature
Given that Q has a single fixed boiling point, Q, is suspected to be a pure substance, and it will therefore also have a fixed single melting point above room temperature;
Therefore, the best option is option C. 116 °C, which is above a single temperature value above 116 °C
