Answer :
When solving problems related to Charles's Law, which describes the relationship between the volume and temperature of a gas at constant pressure, it is recommended to use the Kelvin scale for temperature measurements. This is because the Kelvin scale is an absolute temperature scale that starts at absolute zero (0 Kelvin or -273.15 degrees Celsius), which is the point where particles have minimal motion.
Using the Kelvin scale ensures that temperature values are always positive and directly proportional to the volume of a gas in Charles's Law. This makes calculations more straightforward and accurate, as it avoids negative temperature values and simplifies the mathematical relationships involved in the law.
Therefore, the correct answer to the question is: a) only the Kelvin scale. It is the most appropriate temperature scale to use when applying Charles's Law in problem-solving scenarios due to its absolute nature and direct correlation with gas volume changes.
