Temperature Variation Coefficient

Click For Summary
SUMMARY

The temperature variation coefficient, denoted as \Psi, is defined in the context of a system containing water and its surrounding environment, represented by room temperature (Troom). The relationship is established through the equations \Delta T / \Delta t = \Psi(T - Troom) and \Psi t = ln((T0 - Troom) / (T - Troom)). The unit of \Psi is determined to be degrees per second, although it is crucial to differentiate between temperature degrees and angular degrees, as they represent distinct measurements.

PREREQUISITES
  • Understanding of thermodynamics and temperature measurement.

Homework Statement


What is the unit of the system-universe temperature variation coefficient?

The system is a container holding a mass of water. T
The universe I guess is the room temperature. Troom
t is time in seconds.
[tex]\Psi[/tex] is the temperature variation coefficient.

Homework Equations


[tex]\Delta[/tex]T / [tex]\Delta[/tex]t = [tex]\Psi[/tex](T - Troom)
[tex]\Psi[/tex]t = ln ((To - Troom) / (T - Troom))

The Attempt at a Solution


Since it is temperature over time I thought that it would be degrees per second? But that is angular velocity so I'm sure that's not it.

Degrees that measure temperatures are different than degrees that measure angles. You may consider them to be entirely different units, even though it's the same word.
