gas
Oxygen is in a gaseous state at 1000 degrees Celsius.
At 1000 degrees Celsius, oxygen exists in a gaseous state. Oxygen gas (O2) is a colorless and odorless gas at this temperature.
gas.
At 1000 degrees Celsius, oxygen exists in a gaseous state. This high temperature well exceeds oxygen's boiling point of -183 degrees Celsius, causing it to be present as a gas.
gas.
At -200 degrees Celsius, oxygen is in a solid state.
At -204 degrees Celsius, oxygen is in a solid state, specifically as oxygen ice.
Yes, at 1000 degrees Celsius, mercury will be in a gaseous state. Mercury has a boiling point of 356.9 degrees Celsius, so it will have transitioned to a gas at 1000 degrees Celsius.
At -50 degrees Celsius, oxygen would be in a gaseous state. Oxygen condenses into a liquid state at temperatures below -183 degrees Celsius.
At a temperature of 20 degrees C (or F, for that matter) oxygen is a gas.
At 1000 degrees Celsius, mercury is in its liquid state as its melting point is -38.83 degrees Celsius and boiling point is 356.73 degrees Celsius.
At 1000 degrees, methane would be in a gaseous state. Methane typically exists as a gas at room temperature and pressure, so at 1000 degrees it would remain a gas.
