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?
