Question

Isaac pours water into one container and liquid acetone Into another. He seals both conclusions. He measures the gas pressure above both liquids. At the same temperature, the pressure of the Ace tone gas is higher the than the pressure of water vapour. Which liquid requires more thermal energy to change from a liquid to a gas? Explained.

Answer 1

Water

Step-by-step explanation:

Acetone has a higher vapour pressure than water because acetone molecules only experience dispersion forces and diploe interactions as the dominant intermolecular forces.

In addition to these mentioned, water molecules are held together by strong hydrogen bonds. Therefore, water has a much lower vapour pressure than acetone and requires greater energy to break these hydrogen bonds and convert the liquid water to gaseous state.
