Use the definition of power as energy / time. Or work / time; it's basically the same thing.
I Did this when I was little too, all you do is w= f(d)The answer is 600J
For an approximate calculation: specific heat capacity for water = 4.18 J/(g*degC) (how much energy is required per gram per change in degrees C) mass = 25g Change in temperature = 60-10 = 50 degC energy required = mass * change in temperature * specific heat capacity = 25g * 50 degC * 4.18 J/(g*degC)
Work is the same as energy, equal to power times time. 500 watts for 2 minutes could be expressed as 1000 watt-minutes, but is more conventionally expressed as 500x120 watt-seconds, otherwise known as 60,000 Joules or 60 kJ.
