Explain how the colors of stars that have different surface temperatures are similar to the colors of a steel bar that is heated to different temperatures?

The colors of stars vary with their surface temperatures, similar to how a heated steel bar changes color as its temperature increases. Cooler stars emit a reddish hue, akin to a steel bar glowing dimly at lower temperatures, while hotter stars appear blue or white, resembling a bright, white-hot steel at higher temperatures. This phenomenon is due to blackbody radiation, where objects emit light at different wavelengths depending on their temperature, resulting in a spectrum of colors that ranges from red to blue as temperature rises.
