Re: deep water = less ejecta?

Also, near the impact site, the material is likely to be in the form of plasma rather than water vapor.

We should also keep in mind that the superheated ejecta would have higher heat capacity than at standard temperature; water vapor at 1000 K, for example, has a heat capacity of 2.288 kJ/kgK (compared to 1.954 kJ/kgK at 500 K).
