As temperature increase the solubility of sodium sulfate decrease
Sodium sulfate is sparingly soluble in ethanol, with a solubility of approximately 0.07 g/100 mL at room temperature.
Sodium sulfate is highly soluble in water, with a solubility of about 49.7g per 100mL of water at 20°C.
Sodium sulfate is unusual in that its solubility becomes largely independent of temp at 49.7 °C( meaning instead of increasing solubility as temp rises it forms a plateau and actually decreases slightly) See the Web Links to the left of this answer for a direct link to a graph of the solubility vs. temperature, as described above.
Some examples of solutes that do not dissolve when warmed include lead sulfate, barium sulfate, and strontium sulfate. These compounds have low solubility in water and do not readily dissolve with an increase in temperature.
The solubility of sodium sulfate in water at 30°C is approximately 49.7 g/100 g of water. Since you have 250 g of water, you can dissolve approximately 124.25 g of sodium sulfate in it at that temperature.

No because the water has lost his solubility
Calcium sulfate (CaSO4) forms a saturated solution first compared to sodium chloride (NaCl) because calcium sulfate has lower solubility in water than sodium chloride. This means that calcium sulfate will reach its maximum solubility point in water sooner than sodium chloride, resulting in the formation of a saturated solution.
Sodium sulfate is highly soluble in water, but insoluble in most organic solvents. If you want to increase its solubility in water (as for any salt), you can heat the solution or remove one of the products (sodium ions or sulfate ions) from solution. I can't think of any insoluble sodium salts, but barium sulfate (BaSO4) is insoluble in water. Thus, adding barium chloride (or some other soluble barium salt) will remove sulfate from the equilibrium (due to BaSO4 precipitation) and increase the solubility of sodium sulfate.
When the temperature increase the solubility also increase.
As temperature increases, the solubility of sodium chloride also increases. This is because higher temperatures provide more energy for the water molecules to break apart the sodium and chloride ions, allowing more sodium chloride to dissolve.
At 25°C, the solubility concentration of sulfate ions (SO₄²⁻) in a saturated solution typically depends on the specific sulfate salt being considered. For example, in the case of barium sulfate (BaSO₄), its solubility product constant (Ksp) indicates that the concentration of sulfate ions in a saturated solution is approximately 0.0001 M. However, for other sulfate salts, such as sodium sulfate (Na₂SO₄), the solubility can be significantly higher. Therefore, the solubility concentration of sulfate ions varies by the specific compound being dissolved.
