Edexcel IGCSE Physics 5 12p Specific Heat Capacity Questions

Practise defining specific heat capacity and explaining temperature changes using mass, energy transfer, gradients and material state changes.

Exam points

state specific heat capacity as energy per kg for a 1 °C or 1 K temperature rise
compare temperature changes when equal masses of air and water gain similar energy
explain different heating-graph gradients using different states and specific heat capacities

[Maximum number: 2]
