Specific Heat Capacity of Water Experiment - GCSE Physics Required Practical
This video allows students to carry out an experiment on the specific heat capacity of water from home. This is a required practical for students to be able to understand and carry out for GCSE Physics.
A 227g beaker of water is heated by an immersion heater. A temperature reading is taken every minute for 10 minutes. The temperature and the energy required to heat the water is plotted on a graph, the gradient of which is used to then calculate the specific heat capacity of water.
The full results as well as a blank table for students to fill in using the video can be found here:

This guy is saving our practicals
Flawless man, just flawless.
can you give the specifications of the immersion heater you are using
Thank you so much. Very useful!
Hello, I hope you can answer my question. Thank you in advance. Is it okay if I use an aquarium water heater instead of an immersion water heater and perform the experiment in a styrofoam box the size of the beaker to prevent heat loss?
This video is perfect! well done
hi. i was doing this experiment in a more controlled environment with high precision temperature measuring equipment and energy meters, vacuum insulated water container, 4.5kg of distilled water-to minimize the errors, i was stirring the water to avoid temperature stratification and every single time i got values for Cp around 4724 J/kgC. I run out of ideas of what could create the difference. Can we find out who and when and how were calculated values for water what we take for granted? i calculated the thermal losses to minute values and still doesn't get even close to the book values for water Cp-the difference is too high. Can anyone please give me an idea?
If I may ask Sir, can you drop the hypothesis, independent, dependent and controlled variables

Is the voltage taken here in rms or peak?
