Question
Which of the following correctly describes how Charles's law relates the temperature and volume of an ideal gas?Multiple choice question.Volume and temperature are inversely related.The relationship is true only at constant pressure.Temperature must be expressed in °C.
Solution
The correct answer is: The relationship is true only at constant pressure.
Charles's Law states that the volume of an ideal gas is directly proportional to its absolute temperature, provided the pressure and the amount of gas remain constant. This means that if the temperature increases, the volume also increases and vice versa. However, this relationship holds true only when the pressure is kept constant. If the pressure changes, the volume may not change in direct proportion to the temperature.
Also, it's important to note that the temperature in Charles's Law must be expressed in Kelvin (K), not in degrees Celsius (°C). This is because the Kelvin scale starts at absolute zero, which is the lowest possible temperature where all thermal motion ceases. In contrast, the Celsius scale starts at the freezing point of water, which is not absolute zero. Therefore, using the Celsius scale could lead to incorrect results.
