Thermal energy and temperature change
Thermal energy and temperature change
When an object's temperature rises, its thermal store increases because energy has been transferred to it. When its temperature falls, energy is transferred away and its thermal store decreases.
Step-by-step lessons on AQA GCSE Physics 1.1.3 Energy changes in systems. Each one builds up to exam-style questions. Build a strong grip on equations, units and Key Stage 3 fundamentals before tackling the more demanding topics like electromagnetism, the particle model of matter and space physics.
