Temperature Kelvin scale contains :
Answer: C
The Kelvin scale contains no negative numbers.
The Kelvin scale starts at absolute zero (0 K = -273.15 °C), the lowest temperature possible, at which the thermal motion of particles is at its minimum. Since no temperature can be lower, every kelvin temperature is zero or positive.
Negative numbers occur on the Celsius and Fahrenheit scales, which have arbitrary zeros. 'No positive numbers' is the reverse of the truth. Zero is the lowest point of the scale, but absolute zero cannot actually be reached, so the defining feature of the scale is the absence of negative values.
