5) A beaker contains 2 grams of ice at a temperature of -10°C. The mass of the beaker may be ignored. Heat is supplied to the beaker at a constant rate of 2200J/minute. The specific heat of ice is 2100 J/kgK and the heat of fusion for ice is 334 x10³ J/kg. How much time passes before the ice starts to melt?
