Answer:
The force of gravity can cause erosion by;
- pulling rocks and other particles down the side of a mountain or cliff
- it can cause landslides which significantly erode an area.
Answer: d. None of the above is false.
Explanation: The reasons are:
Intermolecular forces should be reduced when molecules need to be vaporized, otherwise they will not be converted into vapours.
When the temperature increases, forces of attraction decreases which allows molecules to evaporate because energy will be increased which allows molecule to break bonding between them. Hence increasing temperature has effect on vaporization.
Dispersion forces is the weakest force between molecules and hydrogen bond is strong so molecule having only dispersion force will evaporate at the higher rate.
