Question

What happens when we heat carbon di oxide?

Answer 1

CO2 decomposes into CO and O2 or into C and O2 .

Answer 2

Very little ... it's a very stable molecule.  Hence its usefulness (in conjunction with its high density) in fire-extinguishers over the years.

In the high temperatures near the bottom of the blast furnace, it will react with hot carbon to produce carbon monoxide:

CO2 + C --> 2CO

Answer 3

It turns into carbon monoxide

Its a colorless, odorless, and tasteless gas.

You can die from inhaling it.
