Heating experiments and Q = mcΔT

Science · Energy · procedural

Plan and carry out experiments to measure energy transferred during heating, including using the equation Q = mcΔT, recording temperature changes over time, and evaluating sources of error

What mastery looks like

  • Uses a thermometer and stopwatch to record temperature change over time in a heating experiment
  • Applies Q = mcΔT to calculate the energy transferred to a substance being heated
  • Identifies sources of energy loss in a heating experiment (e.g. heat to surroundings) and suggests improvements
  • Plots a temperature-time graph and identifies the energy transfer rate from its gradient

Check your understanding

If Heating experiments and Q = mcΔT heated 100 ml of water in a beaker and recorded the temperature every minute, could they plot the results on a graph and use the data to work out roughly how much energy was transferred to the water?
