B) The intensity of radiation would increase greatly, and the color would change from red through white to blue.
C) The intensity of radiation would increase greatly, while the color would remain a dull red.
D) The intensity of radiation would increase only slightly, while the color would change from red through white to blue.

Question

Quizplus · Accepted Answer

As the metal is heated slowly from 500 K to 1500 K, it will emit more radiation due to the increase in temperature. This increase in radiation will cause the color of the emitted light to shift from a dull red to white and eventually to blue. Therefore, the intensity of radiation would increase greatly, and the color would change from red through white to blue.
