Identify the physical states of ethanol at 0°C
At 0°C, ethanol can exist in both liquid and solid states. It will be in a liquid state if its temperature is higher than its freezing point (-114.1°C), and in a solid state if its temperature is lower than its freezing point. However, at atmospheric pressure (1 atm), ethanol will not be in a gaseous state at 0°C as its boiling point is 78.37°C.
Solid
At 0°C, ethanol can exist in a solid state or be frozen as a crystalline material. Its freezing point is -114.1°C and therefore, at 0°C, ethanol will certainly be in a solid state. This solid state of ethanol at 0°C is also known as its freezing point.
To identify the physical states of ethanol at 0°C, we need to know its melting point and boiling point. Ethanol, also known as ethyl alcohol, is a common alcohol found in beverages and fuels.
The melting point of ethanol is -114.1°C, which means that below this temperature, ethanol exists as a solid. However, we are interested in the state of ethanol at 0°C, which is higher than its melting point.
The boiling point of ethanol is 78.37°C. At this temperature and above, ethanol exists as a gas. However, we also know that it is not boiling at 0°C, as 0°C is below its boiling point.
Therefore, at 0°C, ethanol exists as a liquid state. It is important to note that ethanol has a freezing point lower than its boiling point, which allows it to remain in liquid state below its boiling point but above its freezing point.
