Your question, I guess, How do vapour and gases differ...
Answer:
1.) Vapour is the changed state of any liquid either due to boiling or evaporation
2.) Vapour are more energetic as they have absorbed the latent heat of vaporization whereas Gases are low in energy because they are already in gaseous form at room temperature.
3.) Vapour have boiling points above room temperature while gases have their boiling point below room temperature.
Answer:
D. Entropy increases in the reaction.
Explanation:
Entropy is the degree of randomness in a system. In the reaction given we go from a solid to a gas, therefore there is an increase in the randomness. This means there is an increase in entropy.
To find the density you must divide the mass by the density.
180kg ÷ 90m³ = 2kg/m<span>³
The density is </span>2kg/m³
