What changes would you expect to see in the resulting spectrum of emitted light from a piece of metal when it is heated slowly in an intense flame from 500 K to 1500 K?
A) The intensity of radiation would decrease and the color would remain the same.
B) The intensity of radiation would increase and its color would change from red through orange toward yellow.
C) The intensity of radiation would increase,and the color would remain the same.
D) The intensity of radiation would remain constant,while the color would change from yellow to orange and red.

Question

Quizplus · Accepted Answer

As the temperature of the metal increases, the intensity of radiation increases and the color of the emitted light shifts towards shorter wavelengths. This means that as the metal heats from 500 K to 1500 K in an intense flame, the intensity of radiation would increase and the color of the emitted light would change from red through orange towards yellow.
