Thermal Physics /Heat - IGCSE Physics Complete Lesson

Thermal properties and Temperature

Thermal expansion of solids, liquids, and gases at constant pressure

Applications and consequences of thermal expansion



Measurement of temperature



How a physical property that varies with

temperature may be used for the measurement of

temperature, and state examples of such properties

Need for and identify fixed points

Structure and action of

Liquid-in-glass thermometers

Sensitivity,range and linearity of thermometer

Structure of a thermocouple

and show understanding of its use

as a thermometer for measuring high

temperatures and those that vary rapidly



Structure of a liquid-in-glass thermometer relates to its

sensitivity,range and linearity



Thermal capacity (heat capacity)



Rise in the temperature of a body to an

increase in its internal energy



Equation thermal capacity = mc

Define specific heat capacity

Equation change in energy = mc∆T

Experiment to measure the

specific heat capacity of a substance

Melting and boiling in terms of energy input

without a change in temperature

Distinguish between boiling and

evaporation
