What was your hypothesis? according to your data, do you think your hypothesis was correct? what is latent heat? how does it show up on a phase diagram? when a substance is absorbing latent heat, what is happening to it? according to your data, what are the melting and boiling points of water? how can you tell? what practical applications are there for this procedure?

This is the answer i got.

  My hypothesis is that the water was going to melt at 25-degrees Celsius and boil at 100-degrees Celsius. It turns out that my hypothesis was almost correct, the ice actually melted a little sooner. It melted at 20-degrees Celsius. So my hypothesis was incorrect.

Latent heat is changing phase, and when a change in phase is accomplished at constant pressure temperature is constant. On the phase diagram, latent heat shows up as a "thermal plateau" where the graph is a flat line for a brief portion. The melting point of the ice was about 20-25 degrees celsius when it started turning into water, and at 100 degrees celsius when it started boiling. I could tell because the ice turned into water and the water got very hot.

The practical applications for this procedure were, ice,a pot,and a stove.
