Question

28 all substances have the same melting point. true or false? properties of matter

Explanation:

Melting point is an intensive property unique to each pure substance (e.g., water melts at 0°C, ethanol at -114°C). Different substances have different melting points due to varying intermolecular forces/atomic arrangements. So the statement "All substances have the same melting point" is false.

Answer:

False
