It's still just hot particles that would cool and disperse over time and distance

Yes and no. Yes, the explosion would keep expanding and any particles in said expansion would keep going out in a sphere until they interacted with something else with mass. However, it would not continue to be a "sphere of death" because as it continued to expand, the particles would be spread over larger and larger distances in a sphere around the original point of explosion. The energy imparted on the particles would dissipate through radiation but the particles themselves would get further and further apart.

I think a good portion of the force is produced by super heated air expanding. Without air it would just be a release of energy that has nothing to push.
