Match the descriptions below with the bond type (sigma or pi bond) that best fits the description. electron density above and below bond axis electron density along bond axis parallel p orbital overlap end-on orbital overlap

Melting 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.
