I would say the higher the temperature of the solvent, the more quickly the solute will desolve.
A. Is the best answer choice here
Hope i helped. Have a great day
(1) Meteorological/Climate factor:
-Rainfall intensity
-Rainfall amount
-Rainfall duration
-Distribution of rainfall over the drainage basin.
(2) Phsyiographic factors (e.g. watershed)
- watershed size
-Watershed shape
-watershed slope
(3) Vegetation
- Dense vegetation leads to less run-off while sparse vegetation leads to more run-off.
(4) Urban development.
- Roads and buildings have do not allow infiltration into the soil. Water will therefore run off directly into the stream, at a very fast rate and in significant volume.
It is the orbit around the Sun.
