Dry ice is used in fire extinguishers. the dry ice is stored in the cylinder in a solid form. when sprayed on a fire it quickly changes into the gas known as carbon dioxide (co2).

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.
