Carbon dioxide is hot only if is heated or is released from a burning reaction.

But in another kind of 'language' carbon dioxide is an 'hot item', because it is a 'warehouse gas' and a main reason for climate change of the last century.
It can be as cold, or as hot as you wish.
Carbon dioxide is a gas at room temperature, so it does not have a specific hot or cold temperature. Its temperature depends on the environment it is in.
In an atmosphere of carbon dioxide, warm carbon dioxide would rise. Since carbon dioxide is better than twice as dense as air, it would need to be really hot before it would rise.

Venus has an atmosphere made up of hot swirling clouds of carbon dioxide, which create an intense greenhouse effect and contribute to its extreme surface temperatures.
Goldsmiths use blowing pipes for the carbon dioxide to escape. If the carbon dioxide remains in its place it cuts of the supply of oxygen because carbon dioxide is heavier than oxygen
Carbon does not react with hot nitric acid due to its inert nature. The oxidation state of carbon in hydrocarbons is generally lower than its highest oxidation state (+4), which is needed for reaction with nitric acid. Thus, carbon remains unreactive towards hot nitric acid.
Venus has a thick carbon dioxide atmosphere, making up about 96.5% of its atmosphere. This high concentration of carbon dioxide contributes to the intense greenhouse effect on the planet, resulting in surface temperatures hot enough to melt lead.
Venus has a hot, turbulent atmosphere dominated by carbon dioxide. The thick atmosphere traps heat, creating surface temperatures high enough to melt lead.

Venus has an atmosphere mostly of carbon dioxide and has a runaway greenhouse effect. Temperatures there are over 460 °C (860 °F).
When hot air is passed through hot coke, two gases that are formed are carbon monoxide (CO) and carbon dioxide (CO2). This process is known as the destructive distillation of coal, where coke is produced as a byproduct along with these gases.
