Explanation:

• For the soda scenario: When a soda is opened, the hiss and bubbles are due to carbon dioxide gas escaping. Gases have no fixed shape or volume and can expand freely.
• For the chocolate bar: Before melting, a chocolate bar has a fixed shape and volume, which are characteristics of a solid.
• For the spilled water: Water spreading out without keeping a shape indicates it has no fixed shape (but has a fixed volume), which is a property of a liquid.
• For the "seeing breath": The mist is actually tiny water droplets (liquid) formed from the water vapor (gas) in the breath cooling and condensing. But the main substance in the context of the question (as per the options S/L/G) and the state we observe (the mist we see) is liquid (the condensed form).
• For the ice cube: An ice cube has a fixed shape and volume, so it is a solid.
