I just need help on the reactivity series stuff please I need to pass my grade check HELP

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.

Describe what happens to the molecules as water goes from ice to liquid to vapor. be sure to explain what happens to the temperature during the phase changes.

When water dissolves sugar, which process is not involved? o dissociation o hydration o surface area of the solute increases sa
