A typical but very cool star might have a temperature of 3100° Celsius.On the Kelvin scale,this is about:
A) 3373 K.
B) 3068 K because 0 K, the freezing point of water, is 32°C.
C) the same number, 3100 K, because the Kelvin and Celsius scales are the same.
D) 2827 K.

Question

Quizplus · Accepted Answer

The Kelvin scale starts at absolute zero, which is -273.15°C. To convert Celsius to Kelvin, you simply add 273.15. Therefore, 3100 + 273.15 = 3373, making choice A the correct answer. Choice B is incorrect because 0 K is actually -273.15°C, not 32°C. Choice C is also incorrect because the scales are not the same; the Kelvin scale is based on absolute zero while the Celsius scale is based on the freezing and boiling points of water. Choice D is also incorrect as it does not match the correct conversion.
