Liquid.
Liquid
The outer core is kept in a liquid state due to a combination of high temperature, estimated to be between 4400°C and 6100°C, and high pressure, estimated to be around 1.4 million atm at the inner boundary with the inner core.
The inner core is solid due to high pressure preventing the temperature from melting the iron-nickel alloy. The outer core is liquid because the lower pressure allows for the metal to remain in a molten state.
At standard temperature and pressure, chlorine will be a gas.
The extremely high pressure at the inner core drives the melting point of the iron and other materials up beyond the temperature of the inner core. Therefore they remain solid. The pressure in the outer core is lower sop the melting point is below the temperature in this region and so it is a liquid.

that depends on the temperature and pressure, at room temperature and pressure argon is a gas
At standard temperature and pressure, chlorine will be a gas.
The extremely high pressure at the inner core drives the melting point of the iron and other materials up beyond the temperature of the inner core. Therefore they remain solid. The pressure in the outer core is lower sop the melting point is below the temperature in this region and so it is a liquid.
The outer core is liquid because it is under high pressure which lowers the melting point of the metals present in it. The inner core is solid because the immense pressure at the Earth's center, combined with the high temperature, keeps the iron and nickel in a solid state.
This depends on the nature of the material, structure, temperature, pressure.
Temperature and pressure
Depends on the temperature and pressure. At room temp and pressure, chlorine is a gas.
Matter changes state because of temperature and pressure. These quantities bring change.
They are in this state due to the high temperatures (they have melted). Also note that they are not liquid in the inner core even at the even higher temperatures because of the intense pressure also acting.
