At STP, a 50.-gram sample of H2O(l) and a 100.-gram sample of H2O(1) have 1. the same chemical properties

2. the same volume

3.different temperatures

4.different empirical formulas

The same chemical properties

Explanation:

Different masses of water at the same temp and pressure will have different volumes and the same empirical formulas and the same chemical properties

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
