Diethyl ether, commonly known simply as "ether," does not have a single fixed temperature but rather characteristic temperatures at which it undergoes phase changes. These critical points define its state as a solid, liquid, or gas under standard pressure.
Key Temperatures of Diethyl Ether
The most significant temperatures associated with diethyl ether are its melting point and boiling point. These indicate the temperatures at which it transitions from a solid to a liquid and from a liquid to a gas, respectively.
Here are the specific temperatures for diethyl ether:
| Property | Temperature (Celsius) | Temperature (Fahrenheit) | Temperature (Kelvin) |
|---|---|---|---|
| Melting Point | −116.3 °C | −177.3 °F | 156.8 K |
| Boiling Point | 34.6 °C | 94.3 °F | 307.8 K |
- Melting Point: At −116.3 °C, diethyl ether transitions from its solid state to a liquid state. Below this temperature, it exists as a solid.
- Boiling Point: At 34.6 °C, diethyl ether boils, meaning it transitions from a liquid to a gaseous state. Above this temperature, it exists as a gas (vapor).
This means that at typical room temperatures (e.g., 20-25 °C), diethyl ether is a clear, colorless liquid, as its temperature is well above its melting point but below its boiling point. Its relatively low boiling point also explains why it evaporates very quickly at room temperature.
