Ethanol has a melting point of -114 °C and a boiling point of 78 °C.Which state of matter would ethanol be with a temperature of -208 °C?SolidLiquidGas

1. Break Down the Problem

To determine the state of matter of ethanol at -208 °C, we need to compare this temperature with the melting and boiling points of ethanol.

2. Relevant Concepts

• Melting Point of Ethanol: -114 °C (below this temperature, ethanol is in solid state).
• Boiling Point of Ethanol: 78 °C (above this temperature, ethanol is in gaseous state).

3. Analysis and Detail

• At temperatures below -114 °C, ethanol is solid.
• Between -114 °C and 78 °C, ethanol is liquid.
• Above 78 °C, ethanol is gas.

Given the temperature of -208 °C, which is significantly lower than -114 °C, we can conclude the following:

1. -208 °C < -114 °C
   • Therefore, ethanol will be in a solid state at -208 °C.

4. Verify and Summarize

The temperature of -208 °C is well below the melting point of ethanol (-114 °C), confirming that ethanol will be in solid form at that temperature.

Final Answer

Ethanol at -208 °C is in a Solid state.
