Question

how does temperature affect the state of water? select three correct answers. water is a solid at temperatures lower than the melting point. water is a gas at temperatures lower the boiling point. water is a gas at temperatures higher than the boiling point. water is a liquid at temperatures between the melting point and boiling point.

Explanation:

1. Analyze each option:

• For "Water is a solid at temperatures lower than the melting point": The melting point of water (ice) is 0°C. Below 0°C, water is solid (ice), so this is correct.
• For "Water is a gas at temperatures lower the boiling point": The boiling point of water is 100°C (at standard pressure). Below 100°C, water is liquid (or solid if below 0°C), not gas, so this is incorrect.
• For "Water is a gas at temperatures higher than the boiling point": Above 100°C (at standard pressure), water turns into steam (gas), so this is correct.
• For "Water is a liquid at temperatures between the melting point and boiling point": Between 0°C (melting point) and 100°C (boiling point), water is in liquid state, so this is correct.

Answer:

A. Water is a solid at temperatures lower than the melting point, C. Water is a gas at temperatures higher than the boiling point, D. Water is a liquid at temperatures between the melting point and boiling point
