Question
- A. The calculated pressure will always be zero.
- B. The results may be inaccurate, leading to incorrect conclusions.
- C. The gas will not behave ideally.
- D. The volume will be calculated as negative.
Answer
The results may be inaccurate, leading to incorrect conclusions.
Explanation
Using inconsistent units in the ideal gas equation can lead to inaccurate results. This occurs because the calculations depend on the correct relationships between pressure, volume, temperature, and the number of moles. If the units do not match, the final results can be misleading, which can lead to incorrect conclusions about the behavior of the gas.
Common mistake
Unit Consistency in Ideal Gas Calculations
Students often forget to convert all values to SI units before using the ideal gas equation.
To fix this, always check that pressure is in pascals (Pa), volume in cubic meters (m³), and temperature in kelvin (K) before performing calculations.
