(Physics) What is a method of an experiment a person can carry out to observe the effect of energy supplied on temperature rise?
please help:)

1. Decide what material you are going to heat - water?, solid metal like aluminium or copper? etc and look up that material's "latent heat" or "specific heat capacity" (shc)
2. Select temperature measuring device with the required accuracy, and the type of probe according to the material selected.
e.g. digital thermometer with Pt100 probe would be suitable for water
3. Decide how to control and/or measure the energy losses during the experiment as this will affect the accuracy of your results. e.g. provide thermal insulation around the heated material?
4. Select your energy source. Electricity is easiest because the power consumed can be accurately measured.
5. Energy = Power x time, so select a suitable timing device, such as a stopwatch.
e.g. 1000W heater * 60 sec = 60000 J of energy supplied.
6. Perform lots of energy supplied vs. temp rise measurements, and analyse the results.
Have fun!
