Heat / Thermal Physics

A)  IGCSE Syllabus: Thermal Physics

B)  SPM: Form 4 Chapter 4 - Heat

Thermal Physics / Heat

Areas Covered (in upcoming posts):

1.    Introduction: Thermal Energy of Matter - Temperature,Mass and Heat Capacities

2.    Kinetic Molecular (Particle) Model of Matter

3.    Evaporation and Boiling

4.    Gas and Gas Laws – Pressure, Volume and Temperature

A)      Pressure and Volume (Boyle’s Law)

a.       Pressure and Volume Relationship

b.      Applications

B)       Pressure and Temperature (Pressure Law)

a.       Pressure and Temperature Relationship

b.      Applications (balloon bursts when subject to heat, etc.)

C)      Volume and Temperature (Charles’ Law)

a.       Pressure and Volume Relationship

b.      Applications (hot air balloon, etc.)

(Do the above gas laws explain why pressure increases when we pump more air into, say, a ball or a tyre? the n in the ideal gas law pv = nRT can explain the missing factor) 

5.    Thermal Expansion: Solid, Liquid and Gas

a.       Heat Capacity

b.      Specific Heat Capacity

c.       Applications of Specific Heat Capacity

C)      Latent Heat and Specific Latent Heat
