A chef, on finding his stove out of order, decides to boil the water for his wife's coffee by shaking it in a thermos flask. Suppose that he uses tap water at 17°C and that the water falls 35 cm each shake, the chef making 35 shakes each minute. Neglecting any loss of thermal energy by the flask, how long (in minutes) must he shake the flask until the water reaches 100°C? The specific heat of water is 4186 J/kg·K.
