Distilled water could be considered this.
What is a pure compound?
400
Heating water on a hot plate causes it to increase in temperature and ultimately boil producing this kind of reaction.
What is physical?
400
This separation technique requires the increase of kinetic energy of particles followed by the decrease of kinetic of particles in a substance.
What is distillation?
400
This transition converts a solid directly to a gas.
What is sublimation?
