Heating and cooling curves;
↳Shows how the temperature changes as a substance is heated at a constant rate.
→ The Y-axis represents the temperature.
→ The X-axis represents the Time.
⇒ The region where the temperature remains constant while heat is absorbed is called the plateau.
The proof of this heating and cooling curves:
↳Kinetic particle theory.
Kinetic particle theory:
→ Matter is made up of particles.
→ Particles have space between them.
→ Particles have kinetic energy.
→ Particles are in motion.
→ Particles collide.
→ Collisions are elastic(Meaning they bounce off)
→ Temperature affects kinetic energy.
→ State changes,
→ Intermolecular forces exist.
This theory explains the phase transition and heating and cooling curves since how something turns out after an increase in heat and a decrease in heat can be explained through this theory.
