To determine the variables in Gay-Lussac's law, let's first understand the basic principle of Gay-Lussac's law. According to this gas law:
"For a given amount of gas at a fixed volume, the pressure (P) of the gas is directly proportional to its absolute temperature (T)."
From this statement, we can identify the key variables and constants:
- The variables that change in Gay-Lussac's law are pressure (P) and temperature (T).
- The volume of the gas and the amount of gas (moles of gas) are kept constant.
Therefore, the variables in Gay-Lussac's law are:
- pressure
- temperature
Thus, when asked "What are the variables in Gay-Lussac's law?" the correct answer is:
- pressure and temperature
That's because these are the two factors that change while studying the relationship governed by Gay-Lussac's law, while the volume remains constant.
