AQA GCSE Physics Heating and Cooling Curves Mixed Calculations Worksheet
AQA GCSE heating and cooling worksheet with answers. Read temperature-time curves and combine thermal-energy, latent-heat and power calculations.
What is covered
Questions and skills covered
The worksheet contains 7 pages of printable questions. A separate 7-page solutions PDF makes it easy to mark, review or share answers after the activity.
- Mass conservation during melting
- Internal energy as total particle kinetic plus potential energy
- Graph state and duration readings
- 300g to0.300kg; temperature differences from negative starting temperatures
- Three heating-stage energies and heating time
- Partial melting after subtracting prior ice-warming energy
- Equation selection for new masses and states
- Temperature rise versus final temperature
- Controlled constant-rate cooling and freezing
- Potential energy increases on melting and decreases on freezing
- Specific heat capacity and graph slope at fixed mass and power
- Electrical input versus net sample heating power
- Insulation choice using a3-hour energy allowance
- A phase change prevents an invalid negative liquid-temperature prediction
About this activity
A mountain-rescue station turns stored ice into warm water, checks a real heater and selects insulation to meet an overnight temperature criterion.
Before you start
After teaching internal energy, phase changes, SHC, SLH and power. Equations and material values supplied. Both-tier core with scaffolded multistage decisions.
A question from the worksheet
Question5(f), pupil page7
A300gwater sample at40°C loses54000J. Why does a one-stage mcΔθ prediction of−2.9°C liquid water fail?
Show the answer
50400J cools it to0°C; the remaining3600J is released by partial freezing. The model ends with ice and liquid at0°C.
Common error: Assuming that every energy transfer changes temperature, using final temperature instead of temperature change, or skipping a latent-heat stage.
