Thermal Properties of Matter
Why metal feels colder than wood at the same temperature, and why the sea warms so slowly.
What this lesson covers
Thermal Properties of Matter is a 8-part Class 9 Physics lesson. Each part makes one point and then hands over to the next, so it can be read in a sitting or picked up again at the part you stopped on. It defines the idea in plain words before using it, works through an example step by step, breaks the topic into its parts and compares them, shows where it is used outside the textbook, names the mistakes that cost marks in an exam, ends with a recap of what to remember.
How it begins
These two words are used interchangeably in daily speech and mean different things in physics. Temperature: the average kinetic energy of the particles. Measured in °C or K. It tells you how hot something is, not how much energy it holds. Heat: the total thermal energy transferred because of a temperature difference. Measured in joules.
The 8 parts
- Heat is not temperature
- Three ways heat travels
- Specific heat capacity
- A heating calculation
- Where it shows up
- Where marks get lost
- What to remember
- Watch one worked through
