Detailed Solution

(a)When temperatures are high and pressures are low, actual gases follow the ideal gas equation PV = RT. Real gases do not always abide by the ideal gas laws, regardless of the temperature or pressure.

(b)At high pressure, a real gas takes up more space than an ideal gas.

(c)Measured and estimated volumes converge at low pressures. <br> High pressures and/or low temperatures are where non-ideal behavior, or divergence from the ideal gas laws, is most noticeable.

The correct answer is A, B, C.
