Answer #1

Answer is E. The volume occupied by gas molecules themselves becomes significant.

When the pressure increases highly the volume occupied decreases and the molecules come closer and occupy less volume so, the volume occupied by molecules becomes significant. Which is completely opposite to idea gas, in ideal gases the volume occupied by molecules compared by total volume is negligible, but in this case due to very pressure volume occupied by molecules becomes significant compared to total volume.

WHY OPTION A CANT BE ANSWER: Pressure is no where related to accuracy of calculations

WHY OPTION B CANT BE ANSWER: Without knowing other parameters we cant say it exist in liquid at that pressure.

WHY OPTION C CANT BE ANSWER: When pressure increases more collisions happen because molecules need to travel less distance due to decrease in volume

WHY OPTION D CANT BE ANSWER: Increase in pressure does not increase attraction forces.

    Which of the following statements is true tor real gases? Choose all that apply. As molecules increase in size, deviations from ideal behavior become more apparent at relatively high pressures. Attractive forces between molecules cause a decrease in pressure compared to the ideal gas. The volume occupied by the molecules can cause a decrease in pressure compared to the ideal gas. As molecules increase in size. deviations from ideal behavior become more apparent at relatively low pressures.

    Part B Review Constants Periodic Table Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average...
