Neptune’s vast body of liquid accounts for most of its volume. Scientists think this pressurized ocean or mantle of slushy ice is composed mostly of water as well as molecules of methane and ammonia. Neptune’s ocean is extremely hot (about 4700°C/about 8500°F). The ocean remains liquid at this temperature instead of evaporating because the pressure deep in Neptune is several million times higher than the atmospheric pressure on Earth.

Uranus's water-ammonia "ocean" is extremely hot, up to 6650°C / 12,000°F near the rocky core (which cannot be directly observed).
