You take a block of granite and heat it to 1000 degrees Kelvin,and it glows bright red.If you then heat it to 1200 Kelvin,how might it look different?
A)It would be brighter and more white.
B)It would be much brighter and red.
C)It would be about the same brightness but white.

Question

Quizplus · Accepted Answer

As the temperature of the block of granite increases from 1000 Kelvin to 1200 Kelvin, the intensity of the emitted light will also increase. The color of the light emitted by the heated granite depends on the temperature, with higher temperatures resulting in a brighter and more white light. So, the block of granite will be brighter and more white at 1200 Kelvin compared to 1000 Kelvin.
