This comprehensive Pearson Edexcel IAL Physics Unit 5 (WPH15/01) Master Revision Guide covers Thermodynamics, Radiation, Oscillations and Cosmology in full. Aligned with the 2019–2025 exam series and based on Principal Examiner Reports (2019–2024).

What’s inside?

Priority heatmap – Critical topics appear every sitting: ideal gas law (pV = nRT, T in K, p in Pa), kinetic theory (½m<c²> = ³⁄₂kT, cᵣₘₛ = √(3kT/m)), specific heat capacity (Q = mcΔθ), specific latent heat (Q = mL), first law of thermodynamics (ΔU = Q + W, sign conventions), radiation attenuation (I = I₀e^(–μx), x½ = ln2/μ), Hubble’s law (v = H₀d, age t = 1/H₀), red shift (z = Δλ/λ = v/c), Doppler effect, damping (light/critical/heavy, amplitude–time graphs), resonance (f_drive = f₀, max amplitude), acoustic impedance (Z = ρc, reflection coefficient = ((Z₂–Z₁)/(Z₂+Z₁))²), PET scanning, and Big Bang evidence.

Top 15 penalised errors – Not converting T to Kelvin in gas laws, not converting p to Pa, using Celsius directly (factor of ~15 error), confusing absorbed dose (Gy) with effective dose (Sv), reflection coefficient missing square, critical vs heavy damping swapped, and H₀ not converted to s⁻¹ for age calculation.

Core practicals (CP13–CP14) – CP13 (specific heat capacity: θ vs t graph, gradient = IV/mc, insulation reduces heat loss), CP14 (Boyle’s law: p vs 1/V graph straight through origin, gradient = nRT).

Mathematical skills – Two-state gas law problems (p₁V₁/T₁ = p₂V₂/T₂), kinetic theory (mean KE, cᵣₘₛ), attenuation (I/I₀, x½), Hubble’s law (v = H₀d, H₀ to s⁻¹ conversion: ×10³ ÷ 3.09×10²²), and age of universe (t = 1/H₀).

Model answers – SHC definition (per unit mass, constant temperature), Big Bang evidence (observation → implication → link), and why increasing T at constant volume increases p (KE → faster molecules → more frequent/harder collisions).

Exam predictions – High-confidence: ideal gas/kinetic theory (multi-step calculation), Hubble’s law + age of universe (unit conversion), Big Bang extended writing (5–6 marks), attenuation + half-value thickness, and damping graph identification.

Teacher tools – Diagnostic activities (gas law with Celsius vs Kelvin, H₀ conversion, damping graphs), common misconceptions register (universe expands into space – false, critical damping less damping than light – false), differentiated revision, and classroom starters/exit tickets.

Pearson Edexcel IAL Physics Complete Revision Bundle | Units 1–6 | WPH11–WPH16 | Mechanics, Materials, Waves, Electricity, Further Mechanics, Fields, Particles, Thermodynamics, Cosmology, Practical Skills & Exam Predictions

This complete bundle contains all six Pearson Edexcel IAL Physics Master Revision Guides for Units 1–6 (WPH11–WPH16). Covering the entire IAS and IA2 specification, this resource is aligned with the 2019–2025 exam series and based on Principal Examiner Reports (2019–2024) – helping students move from grade U to A*. What’s inside each guide? Unit 1 (WPH11/01) – Mechanics and Materials Unit 2 (WPH12/01) – Waves and Electricity Unit 3 (WPH13/01) – Practical Skills in Physics I Unit 4 (WPH14/01) – Further Mechanics, Fields and Particles Unit 5 (WPH15/01) – Thermodynamics, Radiation, Oscillations and Cosmology Unit 6 (WPH16/01) – Practical Skills in Physics II Key features across all units: Priority heatmaps – Critical topics (★★★★★) appear in every sitting. Revise these first. Top 15 penalised errors per unit – Direct from examiner reports: missing units, gradient from data points (not line), SUVAT with non-constant acceleration, confusion between elastic limit and limit of proportionality, diameter vs radius, EMF vs terminal pd, nodes/antinodes spacing, TIR conditions, coherence definition, SHM definition missing both conditions, capacitor energy missing ½, Lenz’s law opposing flux (not change in flux), gas laws with Celsius (not Kelvin), H₀ not converted to s⁻¹ for age, and vague improvements (“use better equipment”). Full worked examples – Step-by-step solutions with examiner commentary for every calculation type. Core practicals (CP1–CP14) – Method, key measurements, graph, dominant uncertainty, improvements. Mathematical skills modules – SUVAT, vector resolution, percentage uncertainty, combining uncertainties, gradient calculation, max/min gradient, linearisation, exponential decay, logarithms, Hubble constant conversion, and binding energy calculations. Model answers – 1-mark to 6-mark extended writing with examiner commentary. Exam predictions – High-confidence predictions for every unit, based on past paper frequency and examiner concern. Teacher planning tools – Diagnostic activities, common misconceptions registers, differentiated revision (three tiers), and classroom starters/exit tickets. How I use this bundle: For students – Start with the priority heatmap for your target unit. Practise calculation questions daily – Units 1–5 have ≥32 marks of maths per paper. For practical skills (Units 3 and 6): master graph plotting (points ON the line for gradient), % uncertainty (for A = πd²/4, %ΔA = 2 × %Δd), and linearisation (rearrange equation into y = mx + c). For teachers – Use diagnostic activities to assign students to weakness profiles. The misconceptions register targets persistent errors across all examiner reports. This bundle includes: Unit 1 (WPH11), Unit 2 (WPH12), Unit 3 (WPH13 – Practical Skills I), Unit 4 (WPH14), Unit 5 (WPH15), and Unit 6 (WPH16 – Practical Skills II). Download now for complete exam preparation – from SUVAT to SHM, from Coulomb’s law to cosmology, from uncertainty to linearisation. Independently produced by Samata Reviews.
