A.CO2 molecules lose mass to become gas.
B.CO2 molecules release heat energy to the air.
C.CO2 molecules absorb heat energy from the air.
D.CO2 molecules react with oxygen and become gas.

Answers

Answer:

A

Explanation:

Carbon dioxide is a gas at room temperature.

When the solid dry ice turns into carbon dioxide gas, the carbon dioxide molecules release heat energy into the air. Thus, the correct option for this question is B.

What happens when the solid dry ice turns into carbon dioxide gas?

When the solid dry ice turns into carbon dioxide gas, the process of sublimation occurs. This process of sublimation significantly converts the dry ice into a gas in the form of water vapor.

It may be revealed that dry ice is known for carbon dioxide in its solid state of matter. The unique property of this dry ice is that it ultimately turns from a solid to gas at room temperature. This is because it provokes water vapor in the air to be condensed into droplets of water thus constructing a fog appearance.

Therefore, the molecules of carbon dioxide release heat energy into the air. Thus, the correct option for this question is B.
