Charles' Law describes the relationship between which two quantities for a fixed amount of gas?

• A. Volume and temperature
• B. Pressure and volume
• C. Pressure and temperature
• D. Volume and number of moles

Answer: (A)

Verified step by step guidance

1. Recall that Charles' Law is one of the gas laws that describes how gases behave under certain conditions.
2. Charles' Law specifically relates the volume of a fixed amount of gas to its temperature, assuming pressure remains constant.
3. The law states that the volume of a gas is directly proportional to its absolute temperature (in Kelvin) when pressure and amount of gas are held constant.
4. Mathematically, Charles' Law can be expressed as \(\frac{V_1}{T_1} = \frac{V_2}{T_2}\), where \(V\) is volume and \(T\) is temperature.
5. Therefore, the two quantities related by Charles' Law are volume and temperature.
