What is the characteristic feature of a substance with a flame temperature of 3600 degrees Fahrenheit?

A flame temperature of 3600 degrees Fahrenheit suggests that the substance exhibits high combustion energy. This value indicates that the substance can produce significant heat during combustion, which is a characteristic of fuels that release a large amount of energy when they burn. High combustion energy correlates with the ability of the fuel to maintain a vigorous and hot flame, making it suitable for applications where intense heat is required.

Understanding flame temperature is essential in evaluating fuel performance; the higher the flame temperature, the more energy is typically released during combustion. This characteristic is particularly important in energy generation and industrial processes, where efficiency and heat output are critical factors.

In contrast, options related to low burning efficiency, low ignition point, or high flame stability do not directly align with the implications of such a high flame temperature. Therefore, the recognition of the correlation between high flame temperature and high combustion energy highlights why B is the correct choice in this context.
