A 20.0 L sample of gas from Mount Kilimanjaro was collected at 10.0 °C and has a pressure of 608 mmHg. How many moles of gas does this sample contain? Give the numerical answer with the correct number of significant figures (sig figs).

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.
