Exercise
Form 14: Endothermic vs Exothermic Phase Changes
In this engaging exercise, students will explore the concepts of endothermic and exothermic phase changes through interactive simulations and real-life examples, helping them understand how energy transfer affects temperature and state changes in matter. By the end, learners will be able to differentiate between these two types of phase changes and apply their knowledge to everyday phenomena.
