So, the question is, they calculate the energy supplied by an immersion heater to raise the temperature of 5 kilograms of water.
00:09
So, the given they have given, the mass is 5 kilograms from 22 to 47 degrees celsius.
00:16
So the initial temperature is 22 degrees celsius and the final temperature is 47 degrees celsius.
00:24
If it takes 75 minutes to raise the temperature.
00:27
So, the time is given, it is 75 minutes.
00:30
And we need to calculate the energy supply.
00:34
So, e is equal to question mark.
00:37
So for finding the e, first we need to find the value of the heat supplied...
