The solubility of a solute decrease with temperature when dissolution is exothermic.

(aq)+Qkcal.
Since heat is evolved, with increase in the temperature, the equilibrium shifts in the reverse direction so as to nullify the effect of increased temperature. Hence, the solubility decreases.

Soil Erosion Simple Definition Soil erosion is a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration in the long term
