Question

The melting point of a solid is the temperature at which it melts, or changes to a liquid. Many substances that you normally think of as liquids or gases have very low melting points! This table shows some of them.

Solid Melting point (°C)
carbon dioxide -78.5
hexane -95.3
ethanol -114

Which shows the solids from lowest to highest melting point?

Answer 1

The solids ordered from lowest to highest melting point are ethanol (-114°C), hexane (-95.3°C), and carbon dioxide (-78.5°C).

Step-by-step explanation:

The question pertains to the melting points of various materials and asks for an ordering from the lowest to the highest melting point. According to the information provided by the student, we have the following substances and their respective melting points: carbon dioxide (-78.5°C), hexane (-95.3°C), and ethanol (-114°C).

To order these from the lowest to the highest melting point, simply arrange the substances in ascending order based on the temperature values given.

1. Ethanol: -114°C
2. Hexane: -95.3°C
3. Carbon Dioxide: -78.5°C

This order shows that ethanol has the lowest melting point, followed by hexane, and then carbon dioxide has the highest melting point among the three substances listed.
