Answer:
116 °C
Explanation:
The given parameters of the Substance Q are;
The boiling point of Q = 445°
The substance <em>Q</em> is a solid at room temperature
Given that <em>Q</em> has a single fixed boiling point, <em>Q</em>, 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
Answer: The boiling point.
Explanation: Once water heats to a boil, it evaporates, turning into water vaper. This is the process in which is called vaporization. Hope that answered your question

Answer:
The other bulb continues to glow with the same brightness
Explanation: If one bulb blows out, it acts as an open circuit. Current does not flow in that branch but it continues to flow in the other branch of the parallel circuit. Hence the other bulb continues to glow. Also the voltage across other bulb remains the same due to which power delivered to it remains the same so it continues to glow with the same brightness.
Explanation:
A. The temperatures of the iron bars after 30 minutes would be less than 160°C because heat would be lost to the surroundings.
