Carbon dioxide.
Carbon dioxide.
Carbon is an element, but not carbon dioxide. Carbon dioxide is a compound of carbon and oxygen.
Dry Ice is frozen carbon dioxide. Carbon dioxide (at atmospheric pressure) changes straight from a gas to a solid when cooled, and straight from solid to gas when warmed. If you filled a bath with dry ice and let it "melt" you would get a bath full of carbon dioxide gas. If you lay in it there is a potential for suffocation as the gas is heavier than air and will have displaced the air from the bath.
A gas cannot boil. Boiling is the transition from liquid to gas.
It's a solid at -78 degrees C (about -109 F). Under standard atmospheric conditions it doesn't melt or boil , it goes directly into a gaseous state. You can liquefy CO2 under presure and it'll boil at about 100 below.
No, ice melts carbon dioxide
Dry Ice. Unlike water, Carbon Dioxide doesn't melt, it sublimates; going directly from solid to gas without going through liquid.

Dry ice, or solid carbon dioxide, camphor are two examples.
the candle uses up the oxygen and in doing so creates carbon dioxide. Eventually there will be more carbon dioxide than oxygen and it will snuff out the flame
Carbon dioxide.
Dry ice is carbon dioxide in solid form. CO2's melting point is -78oC
Malic acid is a solid at 100 C. It will melt and then decompose into carbon monoxide and carbon dioxide at 130 C.
Carbon dioxide.
Methane is another gas that is partly caused by humans, just like carbon dioxide. We generate methane from agriculture, especially cattle farming, and when we cause frozen tundra to melt.
