Answer:
C) The space between the particles remains the same.
Step-by-step explanation:
The figure is missing - find it in attachment.
The figure represents the change of phase from liquid state to gas state (evaporation). In fact, we can see that:
- At the beginning, atoms are close to each other but are not tightly bound --> this means that the substance is in liquid state
- At the end, atoms are free to move far apart from each other --> the substance is now in gas state
After a phase change from liquid to gas:
- The average kinetic energy of the atoms increases (because now they can move faster)
- As a consequence, the temperature (which is related to the average kinetic of the atoms) increases as well
- Since the distance between the atoms is larger, the attractive force between them is smaller
Therefore, the only false statement is
C) The space between the particles remains the same.
In fact, we can easily see from the picture that this is not true, as the distance between the particles increases.
