© Copyright Pearson Prentice Hall Slide 2 of Ideal Gases Solid carbon dioxide, or dry ice, doesn’t melt. It sublimes. Dry ice can exist because gases don’t obey the assumptions of kinetic theory under all conditions. You will learn how real gases differ from the ideal gases on which the gas laws are based.

© Copyright Pearson Prentice Hall Slide 4 of Ideal Gases > Ideal Gas Law To calculate the number of moles of a contained gas requires an expression that contains the variable n.

Slide 5 of 18 © Copyright Pearson Prentice Hall Ideal Gases > 14.3 Ideal Gas Law The gas law that includes all four variables—P, V, T, and n—is called the ideal gas law. The ideal gas constant (R) has the value 8.31 (L·kPa)/(K·mol).
