Specific Heat Capacity & Latent Heat Explained | A Level Physics

Why can a heater keep transferring energy while the temperature stays constant? Learn when to use Q = mcΔθ and Q = ml, how to account for heat losses, and how to split a thermal calculation into physical stages. This A level Physics lesson covers specific heat capacity, continuous-flow calorimetry, specific latent heat of fusion and vaporisation, practical control methods, and a worked example of melting 0.50 kg of ice and warming the water to 20 °C. It also explains why water and steam at the same temperature have different internal energies. 00:00 Same energy, different results 00:25 System and internal energy 00:51 Specific heat capacity and Q = mcΔθ 01:33 Electrical heating and losses 01:51 Continuous-flow method 02:42 Why temperature stays constant 03:20 Specific latent heat and Q = ml 03:49 Fusion: control experiment 04:14 Vaporisation: two-power method 04:39 Worked example: ice to warm water 05:25 Water and steam at the same temperature 05:45 Choose the equation for each stage 06:07 Practice and next lesson https://inklearning.co.uk/physics/the... https://inklearning.co.uk/physics/the... https://inklearning.co.uk/physics/the... #ALevelPhysics #ThermalPhysics #InkPhysics
