GCSE Physics notes: Thermal energy stores and heat transfer

TYPES OF ENERGY STORE - examples explained

(g) Thermal energy stores

Doc Brown's GCSE 9-1 Physics Revision Notes

Suitable for GCSE/IGCSE Physics/Science courses or their equivalent

 This page will help you answer questions such as ...

 What is a thermal energy store?

 Can you describe examples of a thermal energy store?

 How can you increase the heat energy content of a thermal energy store?

 



Thermal energy (heat energy) and thermal energy stores

  • The hotter an object, the more thermal/heat energy the material contains/holds/stores and hot objects can release heat energy to cooler surroundings.

  • Thermal energy can only move from a higher temperature material to a lower temperature material - there must be a negative temperature gradient for a net flow of heat energy.

  • Thermal energy is due to the vibration of atoms in solids or the kinetic energy of particle movement in liquids or gases.

    • S 'heat' is all about the kinetic energy of individual atoms or molecules.

  • Heat energy from a heat energy store can only flow from a higher temperature region to a lower temperature region ie from hot objects to cold objects.

  • Increasing an objects temperature increases its thermal energy store.

  • The increase in the thermal energy store is proportional to the rise in temperature.

  • See Introduction to heat transfer - conduction (and thermal conductivity), convection and radiation GCSE physics notes

  • and Specific heat capacity: how to determine it, use of data, calculations and thermal energy stores
