Hot soot can glow; chemical species can emit characteristic colors. Color alone does not give an exact temperature or prove safety. Compare the readings, and keep conclusions tied to their stated points.

Worked example

In the lesson, two yellow records read 900 C and 1100 C. The second is 200 C higher because 1100 - 900 = 200, not because of its color. C means degrees Celsius.

Fictional table: J is blue, 800 degrees Celsius at point R. K is yellow, 950 degrees Celsius at point S. L is yellow, 800 degrees Celsius at point T.
Invented readings at separate points; not universal temperatures for these colors.

Explain the evidence

The table is invented for practice, not a temperature chart for flame colors. Explain why K has a higher reading than J, then explain why a new blue flame cannot be assigned 800 C. A helper reviews your reasoning separately. Do not light, touch, or add chemicals to flames.

Question 1 Which point has the highest recorded temperature in the table?
Question 2 How much higher is the reading for K than for J?
Question 3 J and L have different visible colors but the same recorded temperature. What does this show about these records?
Question 4 Which process can contribute yellow or orange light in a flame?
Question 5 A new photograph shows a blue flame with no measurements. Which claim is justified?
