Answer

Answer:

  1. Gallium
  2. Remains a gas
  3. Gas

Explanation:

Step1: Analyze gallium's state change

The room - temperature range is from 25°C to 33°C. Gallium's melting point is 30°C. When the temperature increases from 25°C (below melting point, solid) to 33°C (above melting point, liquid), gallium changes from a solid to a liquid.

Step2: Analyze nitrogen's state change

Methane freezes at - 183°C and nitrogen's melting point is - 210°C and boiling point is - 196°C. When cooled from - 170°C to - 200°C, since - 200°C is above its melting point (-210°C) and below its boiling point (-196°C), nitrogen remains a gas.

Step3: Analyze gold's state change

Gold's boiling point is 2,856°C. When heated to 2,856°C, it changes from a liquid to a gas.
