What is room temperature in this context? The temp of the space it's sitting in or a typical room temp on Earth?

Room temperature on earth. In physics room temperature is used as a technical term and actually pretty universally defined as 20°C (293.15 K).

Traditionally in European papers it used to be 18°C, so if Einstein and Schrödinger talk about room temperature it is that.

I've heard in chemistry and stamp collecting they use 25°C but that is heresy.
