Which of the following statements is true? A. Ideal gas law is valid only at very high pressure B. Ideal gas law predicts liquefaction of gases C. The pressure of real gases can be higher than that of ideal gas due to attraction forces between the gas molecules D. Ideal gas law considers the actual volume occupied by the molecules E.
