Question

why is the solubility of oxygen higher in cold water

Answer 1

cold water can hold more dissolved oxygen than warm water and fresh water can hold more dissolved oxygen than salt water .so that warmer and Salter the water ,the less dissolved oxygen there can be....photosynthesis can cause the water to have more dissolved oxygen than the saturation amount

Answer 2

☆HEY MATE HERE IS UR ANSWER☆
______________________________

⇛FOR GASES SOLUBILITY DECREASES AS TEMPERATURE INCREASES.

⇨Since, oxygen is a gas, its solubility depends on the temperature.

⇨It is seen that cold water has much more less temperature as compared to warm water.

⇨Therefore, oxygen is more soluble in cold water than warm water.
