ELI5: Why are there more visible air bubbles in tap water when it is cold outside?
gpt
Gasses are more soluble in a liquid like water when it is really cold, and its solubility goes down as temperature increases. In hot water, a lot of those dissolved gas bubbles have left the water, whereas in cold water, the gas bubbles stay dissolved in the water easily. Thats why you see more bubbles in cold water than in hot water.
