Have you ever wondered how hot you'd have to melt gold to get it to evaporate? Or whether you can freeze helium? Play around with liquids, solids and gasses at different temperatures and in different containers (a jar with a lid, a bear-shaped container, a colander -- all have different properties!) to see what happens! You can add labels to identify the different substances that you're playing with and move a slider to reveal tiny dot representing the molecules moving at different speeds. As with all of Tinybop's Explorer's Library apps, there is no right or wrong way to interact with the elements on the screen, simply explore and discover at your own pace!
