![]() Heat What is it? Heat is thermal energy that flows from an object or substance at a higher temperature toward an object or substance at a lower temperature. Give me an example! Have you ever watched an ice cube melt on a hot sidewalk? Heat is being transferred from the sidewalk into the ice cube, which causes the molecules inside the ice crystals to break apart and turn into liquid water. Copyright ©2010, PCS Edventures, Inc.
