The boiling point of carbon dioxide is -57 °C (or 216.6 K, or -70 °F), but this will only take place at pressures in excess of 5.1 atmospheres. It turns out that CO2 doesn't like to hang around in liquid form unless it is under a good deal of pressure. It will sublime (change directly from a gas into a solid) at anything above −78 °C, and deposit directly as a solid from the gas at anything below −78 °C. In environments without elevated pressure, it changes state from solid to gas and gas to solid (depending on temperature) directly without going through a liquid phase.
Added:
At 1.0 bar, normal pressure, it sublimes (solid-gas phase change) at -78 °C, 194.7 K without passing through its liquid phase.
At 5.185 bar the boiling point (from liquid) is -57 °C, 216.6 K.

What is the Freezing point of carbon monoxide?
The freezing point of carbon monoxide is around -205.1 degrees Celsius (-337.18 degrees Fahrenheit).
What happens when carbon monoxide is cooled?
When carbon monoxide (CO) is cooled, it undergoes a phase transition from a gas to a liquid at its boiling point of about -191.5°C (-312.7°F). As it cools further, it can solidify into a crystalline form known as solid carbon monoxide at approximately -205°C (-337°F). In both liquid and solid forms, carbon monoxide retains its molecular structure, but its physical properties change significantly, such as density and viscosity.
Does carbon monoxide have a melting point?
Carbon monoxide does not have a melting point because it is a gas at room temperature and pressure. It directly transitions from solid to gas in a process called sublimation, without passing through the liquid state.
What is the boiling point of carbon trioxide?
Carbon trioxide is not a stable chemical compound.
What is the boiling point of F and C?
The boiling point of fluorine (F) is -188.12 degrees Celsius (-306.62 F). The boiling point of carbon (C) in the form of a diamond is about 4027 degrees Celsius (7281 F). This value will vary depending on how the carbon is formed.
why carbon monoxide exist as a gas at room temperature?
it has a very low boiling point which is affected by its bonding

Why is the melting and boiling point of carbon dioxide the same -78degree?
They aren't the same. The boiling point of carbon dioxide is -57 oC. (Wikipedia)
What is the boiling point of F and C?

Are carbon monoxide have no intermolecular forces?
Carbon monoxide does have intermolecular forces. The molecule is polar due to the difference in electronegativity between carbon and oxygen, leading to dipole-dipole interactions. These intermolecular forces contribute to properties such as boiling and melting points.
If carbon monoxide is polar why is its boiling point so low?
because it was a small molecular mass. i.e it was a small electron cloud size. hence its intermolecular forces of attraction is weaker and less extensive. less energy is needed to break the int molecular bonds hence low b.p
Will CO be a gas at room temperature?
Assuming a normal pressure, yes, CO will be a gas a room temperature because its boiling point is at -191.5 deg C.
What is the melting and boiling point of carbon-14?
The melting point of carbon is 3 500-4 000 0C in an inert atmosphere and at very high pressure. The boiling point may be a little higher. These data are unsure because carbon can sublime and measurements are difficult and probable inconclusive.
What is abbreviation for carbon monoxide?
The chemical symbol for carbon monoxide is CO.
