Mar 30, 2021 · It’s easy to find examples of Charles’s law in everyday life. Hot air balloons fly based on Charles’s law. Heating the air in the balloon increases the balloon’s volume. This decreases its density, so the balloon rises in the air. To come down, chilling the air (not-heating-it) allows the balloon to deflate.
A base is a substance that forms hydroxide ions OH - when dissolved in water. For example, hydrochloric acid ( HCl HCl) is an acid because it forms H+ H + when it dissolves in water. HCl(g) Water H+(aq) +Cl−(aq) H C l ( g) Water H + ( a q) + C l − ( a q) Similarly, NaOH is a base because it forms OH - when it dissolves in water.
