Heating experiments and Q = mcΔT

“If your child 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?”

0 / 4 mastered

• ⬜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
