Internal energy, heat and temperature

Internal energy, heat and temperature

In thermal physics, you first choose a system, such as gas in a cylinder or a metal block. Everything else is the surroundings, and the system's internal energy is the sum of the random kinetic and potential energies of its particles. This is microscopic energy, not the kinetic energy of the whole object moving from place to place.

Step-by-step lessons on Eduqas A Level Physics Thermal Physics. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- a minimum of 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
