1 Why can a good blacksmith judge the temperature of a piece of heated iron by its color?
A blacksmith can judge the temperature of heated iron by its color because as the temperature increases, the iron will emit different colors of light due to its thermal radiation. This phenomenon is known as incandescence, and each color corresponds to a specific temperature range, allowing the blacksmith to estimate the temperature of the iron based on the color it is emitting.
What color is a star with a surface temperature above 30000 degrees?
A star with a surface temperature above 30,000 degrees Kelvin would appear blue in color. The color of a star is directly related to its temperature, with hotter stars emitting more energy in the blue and ultraviolet parts of the spectrum.
What is the color of stars that have a surface temperature of 3000 degrees celsius?
Stars with a surface temperature of around 3000 degrees Celsius appear red in color. This is because their lower temperature causes them to emit more red and infrared light compared to higher temperature stars.
What are the temperature and brightness of stars indicated by?
The temperature of a star is indicated by its color, with blue stars being hotter than red stars. The brightness of a star is indicated by its apparent magnitude, with lower numbers representing brighter stars.
What colour is oxygen at room temperature?
Oxygen is a colorless gas at room temperature. It does not have a specific color of its own.
