Homework Help: Chemistry

When a sample is above critical temperature and above critical pressure, it is a supercritical fluid.

What happens when a sample is above critical temperature but below critical pressure? What phase is that?

What happens when a sample is above critical pressure but below critical temperature? What phase is that?

"Discuss what would be observed as a sample of water is taken along a path that encircles and is close to its critical point."

Obviously, when a sample crosses the gas-liquid phase boundary, standard evaporation or condensation will occur. But how about the rest of that cycle?
