Under what condition does a real gas behave most nearly like an ideal gas?
AAt low temperature or high pressure
BAt high temperature or low pressure
COnly at absolute zero temperature
DAt low temperature and low volume
Answer & Solution
Correct answer: B. At high temperature or low pressure
1. A gas is ideal when intermolecular forces are negligible.
2. These forces weaken when molecules are far apart and fast moving.
3. This happens at high temperature or low pressure.
4. Low temperature with high pressure strengthens the forces, the opposite condition, so that is wrong.
