I need help with these questions. The time is 4 minutes and 46 seconds.
Data Section
Table 1: Heat Lab Data
Mass of Water (kg) Room Temperature (°C) Time Until Boil (s)
500 25 14:46:87
Boiling Temperature (°C)
100.0°C
Questions Section
1) Calculate how many Joules of energy Q was required to heat the water from room temperature to boiling.
2) Using the total time it took for your stovetop burner to heat the water, calculate the effective wattage (1 Watt = 1 J/s) of your stovetop burner.
3) Both natural gas and burners output approximately 3000 Watts of power while in use.
4) Based on your answer from Question 3, how efficient are stovetops in general? Also, are there ways to minimize energy loss or trap the energy more efficiently?
