Heating Device_____________________ Volume of water __________________ mL Energy Input Initial Time __________ (min)
Final Time__________(min) Change in Time_________(min)
Power _________ (Watts) Convert the change in time in minutes to hours t (min)/60 (min/hour) Change in Time ________________ (hours) This will be a decimal To determine energy input in calories multiply time in hours by the wattage during heating. Then multiply by 860 calories/watt*hour to convert to calories Energy Input ________________ cal Useful Energy Output Before Heating Initial Temperature _________ F
(T ‐32)/1.8 = ______________ C
After Heating Final Temperature __________F
(T ‐32)/1.8 =
Change in Temperature
______________C _____________C
To calculate the useful energy output, multiply the change in Temperature C by the volume of water to get the energy change in calories. Useful Energy Output ____________cal Adapted from Lets Have Tea Activity 3.11 Global Science
Energy Efficiency (%) Divide the useful energy output (cal) by the energy input (cal) and multiply by 100%. Energy Efficiency of ________________ is _____________% Use your hot water to make hot chocolate!
