Final answer:
The statement is false; a blue flame is hotter than a yellow or red flame because blue light has a higher frequency, indicating hotter and more complete combustion.
Step-by-step explanation:
The statement that more heat is produced in the secondary flame than in the primary flame but the temperature is much lower is false. In combustion, such as a flame on a stove, the color indicates the temperature of the flame due to the peak frequency of the light emitted. When comparing flames, like the yellowish flame of a peach-scented candle and the bluish flame of a Bunsen burner, we can determine which has a higher temperature. A blue flame typically indicates a hotter, more complete combustion than a yellow or red flame. Therefore, a blue flame, as seen on a Bunsen burner, is hotter. This aligns with the observation that when comparing two flames on a stove, the blue flame is hotter (d. the blue flame is hotter because blue light has a higher frequency).
