Charcoal is almost 100% carbon. If a 20g of charcoal is burned in air with plenty of oxygen, predict what will happen to the mass of charcoal after burning.

1.solid

2.carbon dioxide

3.helium

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
