Question 1: What is the relationship between pressure and volume of a gas at constant temperature?
Answer: The relationship is inversely proportional, as described by Boyle's Law (P1V1 = P2V2). This means that as the pressure on a gas increases, its volume decreases, and vice versa, provided the temperature remains constant.
Question 2: How does the volume of a gas change with temperature at constant pressure?
Answer: The volume is directly proportional to the temperature, as described by Charles's Law (V1/T1 = V2/T2). This means that as the temperature of a gas increases, its volume also increases, provided the pressure remains constant.
