Does a substance at -1°C and the same substance at 1°C heat up and cool off at the exact same rate when placed into an environment that is 0°C?

Nope. Heat exchange rate by conductivity and/or convection changes *non linearly* based on the temperature of both the substance and the environment. Even in the same environment, the same substance does not behave the same at different temperatures, it's not a simple linear proportion. Also, this is more thermodynamics and phisics than chemistry.
