How to model bubble expansion and multiphase flow

Hello.
I am modeling material ejection due to bubble expansion. I want to know two things:
1. Can COMSOL model the bubble gas phase with a given pressure, density etc which vary based on a given equation such as ideal gas law?
2. If I model bubble phase as a ideal gas, the surrounding coating as a liquid phase, and the material beneath the liquid as a air phase, totally we have three phases in the problem. I find in COMSOL there is a two-phase level set module which can solve the two-phase flow problem. Is there any module which can handle more than three phases problem?

Thanks

Wei
