Final answer:
A sample of neon gas will behave most like an ideal gas at high temperature and low pressure (B), as under these conditions, the ideal gas assumptions are more applicable.
Step-by-step explanation:
At which temperature and pressure will a sample of neon gas behave most like an ideal gas? The correct answer is B) High temperature, low pressure. A real gas behaves more like an ideal gas under these conditions since the particles have enough kinetic energy to overcome intermolecular forces and the volume of the gas particles becomes negligible compared to the total volume of the gas.
Real gases depart from ideal behavior under conditions of low temperature and high pressure, where the volume of gas particles is not negligible and the intermolecular forces between particles become significant.
