At 1000 degrees Celsius, methane (CH4) would primarily exist as a gas, given its boiling point of -161.5 degrees Celsius. At such a high temperature, methane can also undergo thermal decomposition, potentially breaking down into carbon and hydrogen or reacting with other substances in a combustion process. Therefore, while it remains a gas, its chemical behavior may change significantly under these conditions.
Gaseous state
The density of methane at 20 degrees Celsius is approximately 0.656 kg/m³, and at 120 degrees Celsius, it is around 0.333 kg/m³. As temperature increases, the density of methane decreases due to the expansion of gas molecules.
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.
Yes, it is possible for methane.
No, at their boiling points liquid nitrogen is colder than liquid methane.
Methane is in a gaseous state at 100 degrees Celsius.
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 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.
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.
At -50 degrees Celsius, methane is in a solid state.
Gaseous state
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.
Methane condenses into a liquid state at a temperature of approximately -259 degrees Fahrenheit (-162 degrees Celsius).
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.
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.
Methane is a gas at standard temperature and pressure, also at room temperature unless the room in question is very cold!
Methane is a gas at 20 degrees Celsius because its molecular structure consists of a single carbon atom bonded to four hydrogen atoms, resulting in a low boiling point of -161.5 degrees Celsius. This allows methane to exist as a gas at room temperature.
