The state of matter in which Methane would be at 25 degrees would be a Gas.

Gaseous state
Methane (CH₄) turns into a solid at temperatures below its melting point of approximately -182.5 degrees Celsius (-296.5 degrees Fahrenheit) at standard atmospheric pressure. At this temperature, methane transitions from a gaseous state to a solid state, forming a crystalline structure known as solid methane. Under higher pressure, the freezing point can change slightly, but it typically remains very low.

Solid
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.
