An illustration of latent heat and steam formation

This figure provided here illustrates how temperature increases as heat is added to water. Let’s assume that we are considering one pound of water at 70 deg F. Let’s see what happens as heat is added to it. Heat being added is shown on the x-axis (horizontal axis), and the corresponding temperature rise is shown on the y-axis (vertical axis).

You can visually see the relationship between the added heat and temperature by pressing on the “Start Adding Heat” button. A description of the process is provided in the next page. Please pay attention to the calculations provided here, since a similar question is asked in the test.
