Final answer:
The statement is true; temperature affects the solubility of solids and gases differently, with most solid solutes becoming more soluble as temperature increases and gases becoming less soluble.
Step-by-step explanation:
The statement that temperature influences the solubility of a solute is true. Solubility, which refers to how much of a solute can be dissolved in a solvent at a given temperature, varies with temperature. For most solid solutes, as the temperature increases, their solubility in a solvent also increases, although this effect can vary widely among different substances. This is visually represented by a solubility curve, showing the relationship between temperature and solubility. However, in the case of gaseous solutes, solubility typically decreases with an increase in temperature. This phenomenon is particularly important in environmental studies because it explains the impact of thermal pollution on natural bodies of water.
