Nice, although use the [code][hide][/code] tag next time. But... (Click to Show Hidden Text)

c is isothermal, e is quasistatic, f is reversible, g is isentropic, and h is cyclic.

Two metal balls of equal mass, one made of aluminum and one made of iron are both at 80 degrees Celsius. They are both dropped into jars that contain equal amounts of water at 20 degrees Celsius. Thermal equilibrium is eventually reached in both jars. Which one of the following statements is true?
a)Both balls will reach the same final temperature
b)The aluminum ball will have a higher final temperature
c)The iron ball will have a higher final temperature

How is the van der Waals equation different from the ideal gas equation? Why?

[MattChina]

How is the van der Waals equation different from the ideal gas equation? Why?

The van der Waals equation is basically a correction for the ideal gas equation. The van der Waals equation takes into account intermolecular forces and molecular size
