Question

why is the melting point and boiling point of carbon diOxide the same​

Answer 1

Answer:

For carbon dioxide, the slope of the solid-liquid equilibrium line is positive; as you raise the pressure, the melting point increases. Carbon dioxide is more dense as a solid than as a liquid, as are most materials. ... So this equilibrium line gives the boiling point as a function of pressure.
