A gas under normal pressure. Methane has a boiling point of -1600C. It does depend on the pressure at extemely high pressures methane will be a liquid.
At 50 degrees Celsius, francium would be in a solid state. Francium is a metal that has a melting point of 27 degrees Celsius. At temperatures lower than its melting point, francium would exist as a solid.
At -50 degrees Celsius, methane is in a solid state.
Methane is a gas at -50 degrees Celsius. It has a boiling point of -161.5 degrees Celsius, so at -50 degrees Celsius, it would be in its gaseous state.
Methane is in a gaseous state at 100 degrees Celsius.
At -50 degrees Celsius, methane remains a gas. Methane has a boiling point of -161.5 degrees Celsius, so at -50 degrees Celsius, it would still be well above its boiling point and would not have undergone a phase change to a liquid.
At 25 degrees Celsius, methane is a gas. Methane has a boiling point of -161.5 degrees Celsius, so at room temperature, it remains in its gaseous state.
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.
Gaseous state
At W degrees Celsius, methane will be in a gaseous state. Methane has a boiling point of -161.5 degrees Celsius, so at temperatures above this, it exists as a gas.
Gaseous state
Methane condenses into a liquid state at a temperature of approximately -259 degrees Fahrenheit (-162 degrees Celsius).
At 25 degrees Celsius, methane exists in a gaseous state, as it has a boiling point of -161.5 degrees Celsius. It is a colorless and odorless gas that is lighter than air.
At 1000 degrees Celsius, methane would be in a gaseous state. Methane is a flammable gas that becomes a superheated gas at high temperatures like 1000 degrees Celsius.
