can change its shape in a continuous manner. So, a rock is not really a uid but when it is heated it becomes one, like lava spurting from a volcano.* It also releases heat that will aect the motion of the uid that is air. Lava denitely can take many dierent shapes. In fact that is why uids are cool. A lava lamp is a good example. e legendary Toronto rock band “Sucker Punch” even has a song called “Cool Like a Lava Lamp.” No really, this song rocks.
