Temperature Change: Convert 29°F to C and K

Click For Summary
SUMMARY

The discussion focuses on converting a temperature change of 29°F into Celsius (C) and Kelvin (K). The correct conversion formula for Celsius is Tc = (5/9)(Tf - 32), which yields a change of approximately 16.11°C for a 29°F increase. Consequently, the Kelvin equivalent is calculated using T(K) = Tc + 273.15, resulting in a change of approximately 289.26 K. The confusion arises from misunderstanding that temperature changes do not require consideration of absolute zero points in the conversion.

PREREQUISITES

Homework Statement


One day you notice that the outside temperature increased by 29° F between your early morning jog and your lunch at noon. What is the corresponding change in temperature in each of the following scales?

_____C
_____K


Homework Equations



Tc = (5/9)(Tf - 32)
T (kelvin) = Tc + 273.15


The Attempt at a Solution



Ti + 29F = Tf
Tf-Ti = 29F

Tc = (5/9)(29-32) = -1.66667C

I am confused to why this answer is incorrect.

If you are only interested in a change of temperature you don't care about the zero points of the scales, you just need to know how many F is a C - and so how many C in 29F
