Use the van der Waals equation of state to calculate the pressure of 3.60 mol of NH 3 at 485 K in a 3.90 L vessel. Use this list of van der Waals constants. P = atm Use the ideal gas equation to calculate the pressure under the same conditions. P = atm

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.
