Glucose, a carbohydrate is used by cells as a primary source of energy and metabolic intermediate. If 100 gram of glucose is oxidised, it releases 1560 kilo joule of energy. Manish is given 100 gram of glucose. Manish utilizes 50 percentage of the gained energy in the event. Rest of the energy is used up in the process of sweating (evaporation). How much quantity of water will Manish have to drink to compensate for this sweating. Consider enthalpy of evaporation of water to be 44 kilo joule per mole.
