Detailed Solution

The above statement is false.
Particles of matter are always in motion. Due to this motion they have some energy, namely kinetic energy. When the temperature is increased then the kinetic energy of these particles increases. The increased kinetic energy of the particles makes the force of attraction between them weaker, thus allowing more solute to get dissolved.
The correct statement would be, Solubility decreases with increase in temperature.
