A. Boyle's law
B. None of these
C. Avogadro's law
D. Charles law
Check answer and explanation
Answer: Charles law
Explanation When pressure is constant, the volume of a gas changes directly with temperature (in Kelvin). As temperature increases, gas particles move faster and occupy more space . This relationship is used to describe gas expansion. It applies only at constant pressure conditions. This is known as Charles’s Law . Last verified on 12-04-2026

A. It forms a salt with sodium hydroxide
B. It has a pH of between 8 and 9
C. It is only partly dissociated into ions
D. It reacts with sodium carbonate to give off carbon dioxide
Check answer and explanation
Answer: It has a pH of between 8 and 9
Explanation Weak acids partially dissociate in water. They have a pH less than 7 , usually around 4–6 . A pH of 8–9 indicates a weak base, not an acid . Weak acids still react with bases and carbonates. Therefore, pH 8–9 is not a property of weak acids . Last verified on 11-04-2026
