By the end you can
Calculate density and measure it for solids and liquids Read heating and cooling curves and explain the flat parts Use E = mL, alone and with E = mcΔθ Explain gas pressure with the particle model Use p₁V₁ = p₂V₂ (Physics only) Analyse the melting ice and heating water practical (Edexcel core practical) Helps with: GCSE (AQA, Edexcel, OCR)
Next unit: Atomic structure and radioactivity Previous unit: Mains electricity, the National Grid and static
