Explanation:

Step1: Identify melting - boiling points

Melting point of chlorine is - 101.6°C and boiling point is - 34.6°C.

Step2: Compare given temperature

Given temperature is - 65°C. Since - 101.6°C < - 65°C < - 34.6°C.

Step3: Determine physical state

When a substance's temperature is between its melting and boiling points, it is in liquid state.

Answer:

Liquid
