12.1 A geyser heats water flowing at the rate of 3.0 liters per minute from 27 °C to 77 °C. If the geyser operates on a gas burner, what is the rate of consumption of the fuel if its heat of combustion is 4.0 × J/g?

Initial temperature, = 27 °C
Final temperature, = 77 °C
Rise in temperature,
Heat of combustion = 4.0 × J/g
Specific heat of water, c = 4.21 J/g/
Mass of flowing water, m = 3 lit/min = 3000 g/min
Total heat used, = 3000 = 6.315 J/min
Rate of consumption = g/min = 15.79 g/min
