Question

Use the table to answer the questions below. When the temperature in a room increases from 25°C to 33°C, changes from a solid to a liquid. In a lab, methane and nitrogen are cooled from -170°C to -200°C. The methane freezes and the nitrogen When gold is heated to 2,856°C it changes from a liquid to a.

Answer 1

Based on the information provided:

• - The change from solid to liquid occurs when the temperature increases from 25°C to 33°C, but the substance undergoing this change is not specified.
• - Methane freezes when cooled from -170°C to -200°C.
• - The change from a solid to a liquid occurs for gold when heated to 2,856°C.

Step-by-step explanation:

Based on the information provided in the table, we can determine the states of matter that substances undergo when subjected to specific temperature changes.

1. When the temperature in a room increases from 25°C to 33°C, a substance changes from a solid to a liquid. However, the table does not provide information about which substance undergoes this change. To determine this, we would need additional information.

2. In a lab, when methane and nitrogen are cooled from -170°C to -200°C, methane freezes. This means that methane changes from a gas to a solid when subjected to this temperature decrease.

3. The table does not provide information about what happens to nitrogen when it is cooled from -170°C to -200°C. Therefore, we cannot determine the change in state for nitrogen based on the given data.

4. When gold is heated to 2,856°C, it changes from a solid to a liquid. This temperature is the melting point of gold, at which it transitions from a solid state to a liquid state.
