Here's why:
* Melting Point: Chloroform's melting point is -63.5 degrees Celsius. This means it transitions from a solid to a liquid at this temperature.
* Boiling Point: Chloroform's boiling point is 61.2 degrees Celsius. This means it transitions from a liquid to a gas at this temperature.
Since -80 degrees Celsius is below chloroform's melting point, it will be in its solid state.
