Question

38.
This temperature is of the surface of the star, the part
of the star which is emitting the light that can be seen.

One way of measuring temperature occurs if an object is
hot enough to visibly glow, such as a metal poker that has
been left in a fire. ( ① ) The color of a glowing object is
related to its temperature: as the temperature rises, the
object is first red and then orange, and finally it gets white,
the "hottest" color. ( ② ) The relation between temperature
and the color of a glowing object is useful to astronomers.
( ③ ) The color of stars is related to their temperature,
and since people cannot as yet travel the great distances to
the stars and measure their temperature in a more precise
way, astronomers rely on their color. ( ④ ) The inter□□□□

Qanda AI · Answer

The passage underscores the idea that **color** is a direct indicator of an object's temperature. As an object heats up from red through orange to white, it emits light corresponding to increasing temperature. Astronomers apply this prin
