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?
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?
Maybe you should calculate losses of heating up of the container itself? along with all the other equipment in the water (i.e. thermometer, stirrer etc. Everything in contact with the water gets heated as well, no? They have a mass, a specific heat capacity according to their material and they increase in temperature. Just a thought...
This guy is saving our practicals
Flawless man, just flawless.
can you give the specifications of the immersion heater you are using

If I may ask Sir, can you drop the hypothesis, independent, dependent and controlled variables
Plssss
Thank you so much. Very useful!

This video is perfect! well done
Is the voltage taken here in rms or peak?
It’s a DC supply
AHHHH YOURE A LIFESAVER!!

thank you so much for the help!!!!
