Since kerosene is a "combustible", it should have a flashpoint ___ degrees Fahrenheit.
A. of less than 32
B. of less than 100
C. between 100 and 200
D. of more than 200
Answer (2)
Combustible materials have a flashpoint at or above 100°F.
Kerosene is a combustible material.
Kerosene's flashpoint is typically between 100°F and 150°F.
Therefore, the answer is \boxed{C}.
Explanation
Understanding the Problem Let's analyze the problem. We are given that kerosene is a combustible material and we need to determine its flashpoint in degrees Fahrenheit. To do this, we need to know the definition of a 'combustible' material in terms of flashpoint.
Flashpoint of Combustible Materials According to standard definitions, a combustible liquid has a flashpoint at or above 100°F (37.8°C). Therefore, kerosene, being a combustible material, must have a flashpoint of 100°F or higher.
Analyzing the Options Now, let's examine the given options: A. of less than 32 B. of less than 100 C. between 100 and 200 D. of more than 200
Option A is incorrect because it's far below the flashpoint of combustible materials. Option B is incorrect because combustible materials have a flashpoint at or above 100°F. Option C is a possible answer, as it falls within the range of combustible materials. Option D is also a possible answer, as it is above 100°F.
Determining the Correct Answer Kerosene typically has a flashpoint between 100°F and 150°F. Therefore, the most appropriate answer is C, between 100 and 200.
Final Answer Therefore, since kerosene is a 'combustible', it should have a flashpoint between 100 and 200 degrees Fahrenheit. The final answer is C.
Examples
Understanding flashpoints is crucial in various real-life scenarios, especially in industries dealing with flammable materials. For instance, consider a chemical engineer designing a storage facility for different types of fuels. Knowing the flashpoints of each fuel helps in implementing safety measures to prevent accidental fires. If a fuel has a flashpoint between 100 and 200 degrees Fahrenheit, like kerosene, the storage area must be designed to maintain temperatures below this range to minimize the risk of ignition. This knowledge is also vital for firefighters and emergency responders who need to assess the potential hazards at the scene of an accident involving flammable liquids. By understanding the flashpoints, they can choose the appropriate extinguishing agents and tactics to safely control the situation.
Kerosene, being a combustible liquid, has a flashpoint typically between 100°F and 150°F. Thus, the correct answer is option C, which states that the flashpoint is between 100 and 200 degrees Fahrenheit. This classification helps ensure proper handling and storage of kerosene to prevent fire hazards.
