1. The problem statement, all variables and given/known data
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.
$$\Psi$$ is the temperature variation coefficient.

2. Relevant equations
$$\Delta$$T / $$\Delta$$t = $$\Psi$$(T - Troom)
$$\Psi$$t = ln ((To - Troom) / (T - Troom))

3. 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.
