Which two temperature changes are equivalent?Multiple Choice: A) 1 K = 1 F degrees B) 1 F degrees = 1 C degrees C) 1 C degrees = 1 K D) none of the above
The conversion relation between Centigrade and Kelvin scale is given by:
C/100 = ( K+273.15)/100
Both C anf K increase or decrease together.
The change one degree in C scale is equal to the change of one Kelvin change in Kelvin scale.
A change by t degree in C scale is also a change of t in kelvin scale.
Change of 1 degree C = Change of one kKlvin
In measurement of temperature the two most common scale are Celsius with symbol C and Fahrenheit with symbol F. In addition these days for a third system called Kelvin with symbol K is used for scientific purposes.
The magnitude of each degree in K and C are same. However in K the 0 temperature is taken as the absolute zero, while that in C the 0 temperature is taken as melting point of ice into water.
In K system the temperature of melting of ice/water is 273.15. Thus:
K = C + 273.15.
From this discussion it is clear that option D) of the question is correct.
