By increasing the temperature, CO2 solubility decreases and you can see CO2 gas bubbles on the surfaces of the water in your test container.
As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase. Therefore, the solubility of CO2 decreases as the temperature increases.
